No. 60/161,137 filed on Oct. 22, 1999, the contents of each of the above are hereby incorporated by reference.
FIELD OF THE INVENTION
This invention relates generally to modulators of chemokine receptor activity, pharmaceutical compositions containing the same, and methods of using the same as agents for treatment and prevention of inflammatory diseases such as asthma and allergic diseases, as well as autoimmune pathologies such as rheumatoid arthritis and atherosclerosis.
BACKGROUND OF THE INVENTION
Chemokines are chemotactic cytokines, of molecular weight 6-15 kDa, that are released by a wide variety of cells to attract and activate, among other cell types, macrophages, T and B lymphocytes, eosinophils, basophils and neutrophils (reviewed in Luster, New Eng. J Med., 338, 436-445 (1998) and Rollins, Blood, 90, 909-928 (1997)). There are two major classes of chemokines, CXC and CC, depending on whether the first two cysteines in the amino acid sequence are separated by a single amino acid (CXC) or are adjacent (CC). The CXC chemokines, such as interleukin-8 (IL-8), neutrophil-activating protein-2 (NAP-2) and melanoma growth stimulatory activity protein (MGSA) are chemotactic primarily for neutrophils and T lymphocytes, whereas the CC chemokines, such as RANTES, MIP-1α, MIP-1β, the monocyte chemotactic proteins (MCP-1, MCP-2, MCP-3, MCP-4, and MCP-5) and the eotaxins (-1,-2, and -3) are chemotactic for, among other cell types, macrophages, T lymphocytes, eosinophils, dendritic cells, and basophils. There also exist the chemokines lymphotactin-1, lymphotactin-2 (both C chemokines), and fractalkine (a CXXXC chemokine) that do not fall into either of the major chemokine subfamilies.
The chemokines bind to specific cell-surface receptors belonging to the family of G-protein-coupled seven-transmembrane-domain proteins (reviewed in Horuk, Trends Pharm. Sci., 15, 159-165 (1994)) which are termed “chemokine receptors.” On binding their cognate ligands, chemokine receptors transduce an intracellular signal through the associated trimeric G proteins, resulting in, among other responses, a rapid increase in intracellular calcium concentration, changes in cell shape, increased expression of cellular adhesion molecules, degranulation, and promotion of cell migration. There are at least ten human chemokine receptors that bind or respond to CC chemokines with the following characteristic patterns: CCR-1 (or “CKR-1” or “CC-CKR-l”) [MIP-1α, MCP-3, MCP-4, RANTES] (Ben-Barruch, et al., Cell, 72, 415-425 (1993), Luster, New Eng. J. Med., 338, 436-445 (1998)); CCR-2A and CCR-2B (or “CKR-2A”/“CKR-2B” or “CC-CKR-2A”/“CC-CKR-2B”) [MCP-1, MCP-2, MCP-3, MCP-4, MCP-5] (Charo et al., Proc. Natl. Acad. Sci. USA, 91, 2752-2756 (1994), Luster, New Eng. J. Med., 338, 436-445 (1998)); CCR-3 (or “CKR-3” or “CC-CKR-3”) [eotaxin-1, eotaxin-2, RANTES, MCP-3, MCP-4] (Combadiere, et al., J. Biol. Chem., 270, 16491-16494 (1995), Luster, New Eng. J. Med., 338, 436-445 (1998)); CCR-4 (or “CKR-4” or “CC-CKR-4”) [TARC, MIP-1α, RANTES, MCP-1] (Power et al., J. Biol. Chem., 270, 19495-19500 (1995), Luster, New Eng. J. Med., 338, 436-445 (1998)); CCR-5 (or “CKR-5” OR “CC-CKR-5”) [MIP-1α, RANTES, MIP-1β] (Sanson, et al., Biochemistry, 35, 3362-3367 (1996)); CCR-6 (or “CKR-6” or “CC-CKR-6”) [LARC] (Baba et al., J. Biol. Chem., 272, 14893-14898 (1997)); CCR-7 (or “CKR-7” or “CC-CKR-7”) [ELC] (Yoshie et al., J. Leukoc. Biol. 62, 634-644 (1997)); CCR-8 (or “CKR-8” or “CC-CKR-8”) [I-309, TARC, MIP-1β] (Napolitano et al., J. Immunol., 157, 2759-2763 (1996), Bernardini et al., Eur. J. Immunol., 28, 582-588 (1998)); and CCR-10 (or “CKR-10” or “CC-CKR-10”) [MCP-1, MCP-3] (Bonini et al, DNA and Cell Biol., 16, 1249-1256 (1997)).
In addition to the mammalian chemokine receptors, mammalian cytomegaloviruses, herpesviruses and poxviruses have been shown to express, in infected cells, proteins with the binding properties of chemokine receptors (reviewed by Wells and Schwartz, Curr. Opin. Biotech., 8, 741-748 (1997)). Human CC chemokines, such as RANTES and MCP-3, can cause rapid mobilization of calcium via these virally encoded receptors. Receptor expression may be permissive for infection by allowing for the subversion of normal immune system surveillance and response to infection. Additionally, human chemokine receptors, such as CXCR4, CCR2, CCR3, CCR5 and CCR8, can act as co-receptors for the infection of mammalian cells by microbes as with, for example, the human immunodeficiency viruses (HIV).
Chemokine receptors have been implicated as being important mediators of inflammatory, infectious, and immunoregulatory disorders and diseases, including asthma and allergic diseases, as well as autoimmune pathologies such as rheumatoid arthritis and atherosclerosis. For example, the chemokine receptor CCR-3 plays a pivotal role in attracting eosinophils to sites of allergic inflammation and in subsequently activating these cells. The chemokine ligands for CCR-3 induce a rapid increase in intracellular calcium concentration, increased expression of cellular adhesion molecules, cellular degranulation, and the promotion of eosinophil migration. Accordingly, agents which modulate chemokine receptors would be useful in such disorders and diseases. In addition, agents which modulate chemokine receptors would also be useful in infectious diseases such as by blocking infection of CCR3 expressing cells by HIV or in preventing the manipulation of immune cellular responses by viruses such as cytomegaloviruses.
A substantial body of art has accumulated over the past several decades with respect to substituted piperidines and pyrrolidines. These compounds have implicated in the treatment of a variety of disorders.
WO 98/25604 describes spiro-substituted azacycles which are useful as modulators of chemokine receptors:
wherein R 1 is C 1-6 alkyl, optionally substituted with functional groups such as —NR 6 CONHR 7 , wherein R 6 and R 7 may be phenyl further substituted with hydroxy, alkyl, cyano, halo and haloalkyl. Such spiro compounds are not considered part of the present invention.
WO 95/13069 is directed to certain piperidine, pyrrolidine, and hexahydro-1H-azepine compounds of general formula:
wherein A may be substituted alkyl or Z-substituted alkyl, with Z=NR 6a or O. Compounds of this type are claimed to promote the release of growth hormone in humans and animals.
WO 93/06108 discloses pyrrolobenzoxazine derivatives as 5-hydroxytryptamine (5-HT) agonists and antagonists:
wherein A is lower alkylene and R 4 may be phenyl optionally substituted with halogen.
U.S. Pat. No. 5,668,151 discloses Neuropeptide Y (NPY) antagonists comprising 1,4-dihydropyridines with a piperidinyl or tetrahydropyridinyl-containing moiety attached to the 3-position of the 4-phenyl ring:
wherein B may be NH, NR 1 , O, or a bond, and R 7 may be substituted phenyl, benzyl, phenethyl and the like.
These reference compounds are readily distinguished structurally by either the nature of the urea functionality, the attachment chain, or the possible substitution of the present invention. The prior art does not disclose nor suggest the unique combination of structural fragments which embody these novel piperidines and pyrrolidines as having activity toward the chemokine receptors.

DEFINITIONS
The compounds herein described may have asymmetric centers. Compounds of the present invention containing an asymmetrically substituted atom may be isolated in optically active or racemic forms. It is well known in the art how to prepare optically active forms, such as by resolution of racemic forms or by synthesis from optically active starting materials. Many geometric isomers of olefins, C═N double bonds, and the like can also be present in the compounds described herein, and all such stable isomers are contemplated in the present invention. Cis and trans geometric isomers of the compounds of the present invention are described and may be isolated as a mixture of isomers or as separated isomeric forms. All chiral, diastereomeric, racemic forms and all geometric isomeric forms of a structure are intended, unless the specific stereochemistry or isomeric form is specifically indicated.
The term “substituted,” as used herein, means that any one or more hydrogens on the designated atom is replaced with a selection from the indicated group, provided that the designated atom's normal valency is not exceeded, and that the substitution results in a stable compound. When a substitent is keto (i.e., ═O), then 2 hydrogens on the atom are replaced.
When any variable (e.g., R a ) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-2 R a , then said group may optionally be substituted with up to two R a groups and R a at each occurrence is selected independently from the definition of R a . Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.
When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such substituent. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

The phrase “pharmaceutically acceptable” is employed herein to refer to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.
As used herein, “pharmaceutically acceptable salts” refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, nitric and the like; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, sulfanilic, 2-acetoxybenzoic, fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, isethionic, and the like.

SYNTHESIS
The compounds of Formula I can be prepared using the reactions and techniques described below. The reactions are performed in a solvent appropriate to the reagents and materials employed and suitable for the transformations being effected. It will be understood by those skilled in the art of organic synthesis that the functionality present on the molecule should be consistent with the transformations proposed. This will sometimes require a judgment to modify the order of the synthetic steps or to select one particular process scheme over another in order to obtain a desired compound of the invention. It will also be recognized that another major consideration in the planning of any synthetic route in this field is the judicious choice of the protecting group used for protection of the reactive functional groups present in the compounds described in this invention. An authoritative account describing the many alternatives to the trained practitioner is Greene and Wuts ( Protective Groups In Organic Synthesis, Wiley and Sons, 1991).
Generally, compounds described in the scope of this patent application can be synthesized by the route described in Scheme 1. The appropriately substituted pyrrolidine (n=0) or piperidine (n=1) 1 is alkylated by a N-protected alkylhalide (halide=Cl, Br, I), mesylate, tosylate or triflate, 2, (where E represents a linkage described within the scope of this application in its fully elaborated form with the appropriate protecting groups as understood by one skilled in the art or in a precursor form which can be later elaborated into its final form by methods familiar to one skilled in the art) with or without base or an acid scavenger to yield the piperidinyl- or pyrrolidinylalkyl protected amine 3. If the halide is not I, then KI can also be added to facilitate the displacement, provided the solvent is suitable, such as an alcohol, 2-butanone, DMF or DMSO, amongst others. The displacement can be performed at room temperature to the reflux temperature of the solvent. The protecting group is subsequently removed to yield amine 4. Protecting groups include phthalimide which can be removed by hydrazine, a reaction familiar to one skilled in the art; bis-BOC which can be removed by either TFA or HCl dissolved in a suitable solvent, both procedures being familiar to one skilled in the art; a nitro group instead of an amine which can be reduced to yield an amine by conditions familiar to one skilled in the art; 2,4-dimethyl pyrrole (S. P. Breukelman, et al. J. Chem. Soc. Perkin Trans. I, 1984, 2801); N-1,1,4,4-Tetramethyl-disilylazacyclopentane (STABASE) (S. Djuric, J. Venit, and P. Magnus Tet. Lett 1981, 22, 1787) and other protecting groups. Reaction with an isocyanate or isothiocyanate 5 (Z=O,S) yields urea or thiourea 6. Reaction with a chloroformate or chlorothioformate 7 (Z=O,S) such as o-, p-nitrophenyl-chloroformate or phenylchloroformate (or their thiocarbonyl equivalents), followed by diplacement with an amine 9, also yields the corresponding urea or thiourea 6. Likewise, reaction of carbamate 8 (X═H, or 2- or 4-NO2) with disubstituted amine 10 yields trisubstituted urea or thiourea 12. Reaction of the amine 4 with an N,N-disubstituted carbamoyl chloride 11 (or its thiocarbonyl equivalent) yields the corresponding N,N-disubstituted urea or thiourea 12. Amine 4 can also be reductively aminated to yield 13 by conditions familiar to one skilled in the art and by the following conditions: Abdel-Magid, A. F., et al. Tet. Lett. 1990, 31, (39) 5595-5598. This secondary amine can subsequently be reacted with isocyanates or isothiocyanates to yield trisubstituted ureas 14 or with carbamoyl chlorides to yield tetrasubstituted ureas 15.
One can also convert amine 4 into an isocyanate, isothiocyanate, carbamoyl chloride or its thiocarbonyl equivalent (isocyanate: Nowakowski, J. J Prakt. Chem/Chem-Ztg 1996, 338 (7), 667-671; Knoelker, H.-J. et al., Angew. Chem. 1995, 107 (22), 2746-2749; Nowick, J. S. et al., J. Org. Chem. 1996, 61 (11), 3929-3934; Staab, H. A.; Benz, W.; Angew Chem 1961, 73; isothiocyanate: Strekowski L. et al., J. Heterocycl. Chem. 1996, 33 (6), 1685-1688; Kutschy, Pet al., Synlett. 1997, (3), 289-290) carbamoyl chloride: Hintze, F.; Hoppe, D.; Synthesis (1992) 12, 1216-1218; thiocarbamoyl chloride: Ried, W.; Hillenbrand, H.; Oertel, G.; Justus Liebigs Ann Chem 1954, 590) (these reactions are not shown in Scheme 1). These isocyanates, isothiocyantes, carbamoyl chlorides or thiocarbamoyl chlorides can then be reacted with R 2 R 3 NH to yield di- or trisubstituted ureas or thioureas 12. An additional urea forming reaction involves the reaction of carbonyldiimidazole (CDI) (Romine, J. L.; Martin, S. W.; Meanwell, N. A.; Epperson, J. R.; Synthesis 1994 (8), 846-850) with 4 followed by reaction of the intermediate imidazolide with 9 or in the reversed sequence (9+CDI, followed by 4). Activation of imidazolide intermediates also facilitates urea formation (Bailey, R. A., et al., Tet. Lett. 1998, 39, 6267-6270). One can also use 13 and 10 with CDI. The urea forming reactions are done in a non-hydroxylic inert solvent such as THF, toluene, DMF, etc., at room temperature to the reflux temperature of the solvent and can employ the use of an acid scavenger or base when necessary such as carbonate and bicarbonate salts, triethylamine, DBU, Hunigs base, DMAP, etc.
Substituted pyrrolidines and piperidines 1 can either be obtained commercially or be prepared as shown in Scheme 2. Commercially available N-benzylpiperid-3-one 16 can be debenzylated and protected with a BOC group employing reactions familiar to one skilled in the art. Subsequent Wittig reaction followed by reduction and deprotection yields piperidine 20 employing reactions familiar to one skilled in the art. Substituted pyrrolidines may be made by a similar reaction sequence. Other isomers and analogs around the piperidine ring can also be made by a similar reaction sequence. Chiral pyrrolidines/piperidines can be synthesized via asymmetric hydrogenation of 18 using chiral catalysts (see Parshall, G. W. Homogeneous Catalysis, John Wiley and Sons, New York: 1980, pp. 43-45; Collman, J. P., Hegedus, L. S. Principles and Applications of Organotransition Metal Chemistry, University Science Books, Mill Valley, Calif., 1980, pp. 341-348).
The cyanoguanidines (Z=N—CN) can be synthesized by the method of K. S. Atwal, et al. and references contained therein (J. Med. Chem. (1998) 41, 217-275). The nitroethylene analog (Z=C—NO2) can be synthesized by the method of F. Moimas, et al. (Synthesis 1985, 509-510) and references contained therein. The malononitrile analog (Z=C(CN)2) may be synthesized by the method of S. Sasho, et al. (J. Med. Chem. 1993, 36, 572-579).
Guanidines (Z=NR 1a ) can be synthesized by the methods outlined in Scheme 3. Compound 21 where Z=S can be methylated to yield the methylisothiourea 22. Displacement of the SMe group with amines yields substituted guanidines 23 (see H. King and I. M. Tonkin J. Chem. Soc. 1946, 1063 and references therein). Alternatively, reaction of thiourea 21 with amines in the presence of triethanolamine and “lac sulfur” which facilitates the removal of H 2 S yields substituted guanidines 23 (K. Ramadas, Tet. Lett. 1996, 37, 5161 and references therein). Finally, the use of carbonimidoyldichloride 24, or 25 followed by sequential displacements by amines yields the corresponding substituted guanidine 23 (S. Nagarajan, et al., Syn. Comm. 1992, 22, 1191-8 and references therein). In a similar manner, carbonimidoyldichlorides, R 2 —N═C(Cl) 2 (not shown in Scheme 3) and R 3 —N═C(Cl) 2 (not shown) can also be reacted sequentially with amines to yield di- and trisubstituted guanidine 23.
A method for introducing substituents in linkage E is that of A. Chesney et al. (Syn. Comm. 1990, 20 (20), 3167-3180) as shown in Scheme 4. Michael reaction of pyrrolidine or piperidine 1 with Michael acceptor 26 yields intermediate 27 which can undergo subsequent reactions in the same pot. For example, reduction yields alcohol 28 which can be elaborated to the amine 29 by standard procedures familiar to one skilled in the art. Some of these include mesylation or tosylation followed by 5 displacement with NaN 3 followed by reduction to yield amine 29. Another route as depicted in Scheme 4 involves reaction with diphenylphosphoryl azide followed by reduction of the azide to yield amine 29.
The mesylate or tosylate can also be displaced by other nucleophiles such as NH 3 , BOC 2 N − , potassium phthalimide, etc., with subsequent deprotection where necessary to yield amines 29. Finally, 29 can be converted to urea or thiourea 30 by procedures discussed for Scheme 1 or to the compounds of this invention by procedures previously discussed. Similarly, aldehyde 27 may be reacted with a lithium or a Grignard reagent 31 to yield alcohol adduct 32. This in turn can be converted to urea or thiourea 34 in the same way as discussed for the conversion of 28 to 30.
Scheme 5 shows that intermediate 36 can be extended via a Wittig reaction (A. Chesney, et al. Syn. Comm. 1990, 20 (20), 3167-3180) to yield 37. This adduct can be reduced catalytically to yield 38 or by other procedures familiar to one skilled in the art. Alkylation yields 39, followed by saponification and Curtius rearrangement (T. L. Capson and C. D. Poulter, Tet. Lett., (1984) 25, 3515-3518) followed by reduction of the benzyl protecting group yields amine 40 which can be elaborated further as was described earlier in Scheme 1 and elsewhere in this application to make the compounds of this invention. Dialkyllithium cuprate, organocopper, or copper-catalyzed Grignard addition (for a review, see G. H. Posner, “An Introduction to Synthesis Using Organocopper Reagents”, J. Wiley, New York, 1980; Organic Reactions, 19, 1(1972)) to alpha,beta-unsaturated ester 37 yields 41 which can undergo subsequent transformations just discussed to yield amine 43 which can be elaborated further to the compounds of this invention as was described earlier. The intermediate enolate ion obtained upon cuprate addition to 37 can also be trapped by an electrophile to yield 42 (for a review, see R. J. K. Taylor, Synthesis 1985, 364). Likewise, another 2-carbon homologation is reported by A. Chesney et al. (ibid.) on intermediate 36 which involves reacting 36 with an enolate anion to yield aldol condensation product 42 where R 12 ═OH. The OH group can undergo synthetic transformations which are familiar to one skilled in the art and which will be discussed in much detail later on in the application. Chiral auxilliaries can also be used to introduce stereo- and enantioselectivity in these aldol condensations, procedures which are familiar to one skilled in the art.
Examples of such methods are taught in D. A. Evans, et al., J. Am. Chem. Soc. 1981, 103, 2127; D. A. Evans, J. Am. Chem. Soc. 1982, 104, 1737; D. A. Evans, J. Am. Chem. Soc. 1986, 108, 2476; D. A. Evans. et al., J. Am. Chem. Soc. 1986, 108, 6757; D. A. Evans, J. Am. Chem. Soc. 1986, 108, 6395; D. A. Evans, J. Am. Chem. Soc. 1985, 107, 4346; A. G. Myers, et al., J. Am. Chem. Soc. 1997, 119, 6496. One can also perform an enantioselective alkylation on esters 38 or 41 with R 12 X where X is a leaving group as described in Scheme 1, provided the ester is first attached to a chiral auxiliary (see above references of Evans, Myers and Mauricio de L. Vanderlei, J. et al., Synth. Commum. 1998, 28, 3047).
One can also react alpha,beta-unsaturated ester 37 (Scheme 6) with Corey's dimethyloxosulfonium methylide (E. J. Corey and M. Chaykovsky, J. Am. Chem. Soc. 1965, 87, 1345) to form a cyclopropane which can undergo eventual Curtius rearrangement and subsequent elaboration to the compounds of this invention wherein the carbon containing R 9 R 10 is tied up in a cyclopropane ring with the carbon containing R 11 R 12 . In addition, compound 48 can also undergo the analogous reactions just described to form cyclopropylamine 50 which can be further elaborated into the compounds of this invention as described previously. Compound 48 may be synthesized by an alkylation reaction of pyrrolidine/piperidine 1 with bromide 47 in an inert solvent employing the conditions as described for the alkylation of 2 onto 1 in Scheme 1.
Another way to synthesize the compounds in the scope of this application is shown in Scheme 7. Michael reaction of amine 1 with an acrylonitrile 51 (as described by I. Roufos in J. Med. Chem. 1996, 39, 1514-1520) followed by Raney-Nickel hydrogenation yields amine 53 which can be elaborated to the compounds of this invention as previously described.
In Schemes 4, 5, and 6, we see that there is no gem-substitution on the alpha-carbon to the electron-withdrawing group of what used to be the Michael acceptor. In other words, in Scheme 4, there is no r 10 gem to R 9 ; in Scheme 5, there is no R 10 gem to one of the R 9 s and in Scheme 7 there is no R 10 gem to R 9 . Gem-substitution can be introduced by reacting pyrrolidine or piperidine 1 with the epoxide of Michael acceptors 26, 35, and 51 to yield the corresponding alcohols (for amines reacting with epoxides of Michael acceptors, see Charvillon, F. B.; Amouroux, R.; Tet. Lett. 1996, 37, 5103-5106; Chong, J. M.; Sharpless, K. B.; J Org Chem 1985, 50, 1560). These alcohols eventually can be further elaborated into R 10 by one skilled in the art, as, for example, by tosylation of the alcohol and cuprate displacement (Hanessian, S.; Thavonekham, B.; DeHoff, B.; J Org. Chem. 1989, 54, 5831), etc., and by other displacement reactions which will be discussed in great detail later on in this application.
Further use of epoxides to synthesize compounds of this invention are shown in Scheme 8. Reaction of pyrrole or piperidine 1 with epoxide 54 yields protected amino-alcohol alcohol 55. This reaction works exceptionaly well when R 7 and R 8 are H but is not limited thereto. The reaction is performed in an inert solvent at room temperature to the reflux temperature of the solvent. Protecting groups on the nitrogen atom of 54 include BOC and CBZ but are not limited thereto. The hydroxyl group can be optionally protected by a variety of protecting groups familiar to one skilled in the art.
Deprotection of the nitrogen by methods familiar to one skilled in the art yields 56 which can be elaborated to the compounds of this invention by the procedures previously discussed. If R 9 ═H, then oxidation, for example, by using 10 PCC (Corey E. J. and Suggs, J. W., Tet. Lett. 1975, 31, 2647-2650) or with the Dess-Martin periodinane (Dess, D. B. and Martin, J. C., J. Org. Chem. 1983, 48, 4155-4156) yields ketone 57 which may undergo nucleophilic 1,2-addition with organometallic reagents such as alkyl- or aryllithiums, Grignards, or zinc reagents, with or without CeC 1-3 (T. Imamoto, et al., Tet. Lett. 1985, 26, 4763-4766; T. Imamoto, et al., Tet. Lett. 1984, 25, 4233-4236) in aprotic solvents such as ether, dioxane, or THF to yield alcohol 58. The hydroxyl group can be optionally protected by a variety of protecting groups familiar to one skilled in the art. Deprotection of the nitrogen yields 56 which can be finally elaborated to the compounds of this invention as previously discussed. Epoxides disclosed by structure 54 may be synthesized enantio-selectively from amino acid starting materials by the methods of Dellaria, et al. J Med Chem 1987, 30 (11), 2137, and Luly, et al. J Org Chem 1987, 52 (8), 1487.
The carbonyl group of ketone 57 in Scheme 8 may undergo Wittig reactions followed by reduction of the double bond to yield alkyl, arylalkyl, heterocyclic-alkyl, cycloalkyl, cycloalkylalkyl, etc. substitution at that position, reactions that are familiar to one skilled in the art. Wittig reagents can also contain functional groups which after reduction of the double bond yield the following functionality: esters (Buddrus, J. Angew Chem., 1968, 80), nitriles (Cativiela, C. et al., Tetrahedron 1996, 52 (16), 5881-5888.), ketone (Stork, G. et al., J Am Chem Soc 1996, 118 (43), 10660-10661), aldehyde and methoxymethyl (Bertram, G. et al., Tetrahedron Lett 1996, 37 (44), 7955-7958.), gamma-butyrolactone Vidari, G. et al., Tetrahedron: Asymmetry 1996, 7 (10), 3009-3020.), carboxylic acids (Svoboda, J. et al., Collect Czech Chem Commun 1996, 61 (10), 1509-1519), ethers (Hamada, Y. et al., Tetrahedron Lett 1984, 25 (47), 5413), alcohols (after hydrogenation and deprotection—Schonauer, K.; Zbiral, E.; Tetrahedron Lett 1983, 24 (6), 573), amines (Marxer, A.; Leutert, T. Helv Chim Acta, 1978, 61) etc., all of which may further undergo transformations familiar to one skilled in the art to form a wide variety of functionality at this position.
Scheme 9 summarizes the displacement chemistry and subsequent elaborations that can be used to synthesize the R 9 groups. In Scheme 9 we see that alcohol 55 or 58 may be tosylated, mesylated, triflated, or converted to a halogen by methods familiar to one skilled in the art to produce compound 59. (Note that all of the following reactions in this paragraph can be also performed on the compounds, henceforth called carbon homologs of 55 or 58 where OH can be (CH 2 ) r OH and it is also understood that these carbon homologs may have substituents on the methylene groups as well). For example, a hydroxyl group may be converted to a bromide by CBr 4 and Ph 3 P (Takano, S. Heterocycles 1991, 32, 1587). For other methods of converting an alcohol to a bromide or to a chloride or to an iodide see R. C. Larock, Comprehensive Organic Transformations, VCH Publishers, New York, 1989, pp. 354-360. Compound 59 in turn may be displaced by a wide variety of nucleophiles as shown in Scheme 9 including but not limited to azide, cyano, malonate, cuprates, potassium thioacetate, thiols, amines, etc., all nucleophilic displacement reactions being familiar to one skilled in the art. Displacement by nitrile yields a one-carbon homologation product. Nitrile 60 can be reduced with DIBAL to yield aldehyde 61. This aldehyde can undergo reduction to alcohol 62 with, for example, NaBH 4 which in turn can undergo all of the S N 2 displacement reactions mentioned for alcohol 55 or 58. Alcohol 62 is a one carbon homolog of alcohol 55 or 58. Thus one can envision taking alcohol 62, converting it to a leaving group X as discussed above for compound 55 or 58, and reacting it with NaCN or KCN to form a nitrile, subsequent DIBAL reduction to the aldehyde and subsequent NaBH 4 reduction to the alcohol resulting in a two carbon homologation product. This alcohol can undergo activation followed by the same S N 2 displacement reactions discussed previously, ad infinitum, to result in 3, 4, 5 . . . etc. carbon homologation products. Aldehyde 61 can also be reacted with a lithium or Grignard reagent to form an alcohol 61a which can also undergo the above displacement reactions. Oxidation by methods familiar to one skilled in the art yields ketone 61b. Displacement by malonate yields malonic ester 63 which can be saponified and decarboxylated to yield carboxylic acid 64, a two carbon homologation product. Conversion to ester 65 (A. Hassner and V. Alexanian, Tet. Lett, 1978, 46, 4475-8) and reduction with LAH yields alcohol 68 which can undergo all of the displacement reactions discussed for alcohol 55 or 58. Alcohols may be converted to the corresponding fluoride 70 by DAST (diethylaminosulfur trifluoride) (Middleton, W. J.; Bingham, E. M.; Org. Synth. 1988, VI, pg. 835). Sulfides 71 can be converted to the corresponding sulfoxides 72 (p=1) by sodium metaperiodate oxidation (N. J. Leonard, C. R. Johnson J. Org. Chem. 1962, 27, 282-4) and to sulfones 72 (p=2) by Oxone® (A. Castro, T. A. Spencer J. Org. Chem. 1992, 57, 3496-9). Sulfones 72 can be converted to the corresponding sulfonamides 73 by the method of H.-C. Huang, E. et al., Tet. Lett. (1994) 35, 7201-7204 which involves first, treatment with base followed by reaction with a trialkylborane yielding a sulfinic acid salt which can be reacted with hydroxylamine-O-sulfonic acid to yield a sulfonamide. Another route to sulfonamides involves reaction of amines with a sulfonyl chloride (G. Hilgetag and A. Martini, Preparative Organic Chemistry, New York: John Wiley and Sons, 1972, p.679). This sulfonyl chloride (not shown in Scheme 9) can be obtained from the corresponding sulfide (71 where R 9d ═H in Scheme 9, the hydrolysis product after thioacetate displacement), disulfide, or isothiouronium salt by simply reacting with chlorine in water. The isothiouronium salt may be synthesized from the corresponding halide, mesylate or tosylate 59 via reaction with thiourea (for a discussion on the synthesis of sulfonyl chlorides see G. Hilgetag and A. Martini, ibid., p. 670). Carboxylic acid 64 can be converted to amides 66 by standard coupling procedures or via an acid chloride by Schotten-Baumann chemistry or to a Weinreb amide (66: R 9a ═OMe, R 9a ′=Me in Scheme 9) (S. Nahm and S. M. Weinreb, Tet. Lett., 1981, 22, 3815-3818) which can undergo reduction to an aldehyde 67 (R 9b ═H in Scheme 9) with LAH (S. Nahm and S. M. Weinreb, ibid.) or reactions with Grignard reagents to form ketones 67 (S. Nahm and S. M. Weinreb, ibid.). The aldehyde 67 obtained from the Weinreb amide reduction can be reduced to the alcohol with NaBH 4 . The aldehyde or ketone 67 (or 61 or 61b for that matter) can undergo Wittig reactions as discussed previously followed by optional catalytic hydrogenation of the olefin. This Wittig sequence is one method for synthesizing the carbocyclic and heterocyclic substituted systems at R 9 employing the appropriate carbocyclic or heterocyclic Wittig (or Horner-Emmons) reagents. Of course, the Wittig reaction may also be used to synthesize alkenes at R 9 and other functionality as well. Ester 65 can also form amides 66 by the method of Weinreb (A. Basha, M. Lipton, and S. M. Weinreb, Tet. Lett. 1977, 48, 4171-74) (J. I. Levin, E. Turos, S. M. Weinreb, Syn. Comm. 1982, 12, 989-993). Alcohol 68 can be converted to ether 69 by procedures familiar to one skilled in the art, for example, NaH, followed by an alkyliodide or by Mitsunobu chemistry (Mitsunobu, O. Synthesis, 1981, 1-28). Alcohol 55 or 58, 62, or 68, can be acylated by procedures familiar to one skilled in the art, for example, by Schotten-Baumann conditions with an acid chloride or by an anhydride with a base such as pyridine to yield 78. Halide, mesylate, tosylate or triflate 59 can undergo displacement with azide followed by reduction to yield amine 74 a procedure familiar to one skilled in the art. This amine can undergo optional reductive amination and acylation to yield 75 or reaction with ethyl formate (usually refluxing ethyl formate) to yield formamide 75. Amine 74 can again undergo optional reductive amination followed by reaction with a sulfonyl chloride to yield 76, for example under Schotten-Baumann conditions as discussed previously. This same sequence may be employed for amine 60a, the reduction product of nitrile 60. Tosylate 59 can undergo displacement with cuprates to yield 77 (Hanessian, S.; Thavonekham, B.; DeHoff, B.; J Org. Chem. 1989, 54, 5831). Aldehyde 61 or its homologous extensions can be reacted with a carbon anion of an aryl (phenyl, naphthalene, etc.) or heterocyclic group to yield an aryl alcohol or a heterocyclic alcohol. If necessary, CeCl 3 may be added (T. Imamoto, et al., Tet. Lett. 1985, 26, 4763-4766; T. Imamoto, et al., Tet. Lett. 1984, 25, 4233-4236). This alcohol may be reduced with Et 3 SiH and TFA (J. Org. Chem. 1969, 34, 4; J. Org. Chem. 1987, 52, 2226) (see discussion of aryl and heterocyclic anions for Schemes 20-22). These aryl and heterocyclic anions may also be alkylated by 59 (or its carbon homolog) to yield compounds where R 9 contains an aryl or heterocyclic group. Compound 59 or its carbon homologs may be alkylated by an alkyne anion to produce alkynes at R 9 (see R. C. Larock, Comprehensive Organic Transformations, New York, 1989, VCH Publishers, p 297). In addition, carboxaldehyde 61 or its carbon homologs can undergo 1,2-addition by an alkyne anion (Johnson, A. W. The Chemistry of Acetylenic Compounds. V. 1. “Acetylenic Alcohols,” Edward Arnold and Co., London (1946)). Nitro groups can be introduced by displacing bromide 59 (or its carbon homologs) with sodium nitrite in DMF (J. K. Stille and E. D. Vessel J. Org. Chem. 1960, 25, 478-490) or by the action of silver nitrite on iodide 59 or its carbon homologs (Org. Syntheses 34, 37-39).
If an anion is made of the pyrrolidine/piperidine 1 with LDA or n-BuLi, etc., then that anion in a suitable nonhydroxylic solvent such as THF, ether, dioxane, etc., can react in a Michael-type fashion (1,4-addition) with an alpha,beta-unsaturated ester to yield an intermediate enolate which can be quenched with an electrophile (R 9 X) (where X is as described in Scheme 1) (Uyehara, T.; Asao, N.; Yamamoto, Y.; J Chem Soc, Chem Commun 1987, 1410) as shown in Scheme 10.
It is to be understood that R 9 is either in its final form or in a suitable protected precursor form. This electrophile can be a carbon-based electrophile, some examples being formaldehyde to introduce a CH 2 OH group, an aldehyde or a ketone which also introduces a one-carbon homologated alcohol, ethylene oxide (or other epoxides) which introduces a —CH 2 CH 2 OH group (a two-carbon homologated alcohol), an alkyl halide, etc., all of which can be later elaborated into R 9 . It can also be an oxygen-based electrophile such as MCPBA, Davis' reagent (Davis, F. A.; Haque, M. S.; J Org Chem 1986, 51 (21),4083; Davis, F. A.; Vishwaskarma, L. C.; Billmers, J. M.; Finn, J.; J Org Chem 1984, 49, 3241) or MoO 5 (Martin, T. et al., J Org Chem 1996, 61 (18), 6450-6453) which introduces an OH group. These OH groups can undergo the displacement reactions discussed previously in Scheme 9 or protected by suitable protecting groups and deprotected at a later stage when the displacement reactions decribed in Scheme 9 can be performed. In addition, these OH groups can also undergo displacement reactions with heterocycles as described for Schemes 19-22 to introduce N- or C-substituted heterocycles at this position. Ester 80 can be converted into its Weinreb amide 82 (S. Nahm and S. M. Weinreb, Tet. Lett., 1981, 22, 3815-3818) or Weinreb amide 82 can be synthesized via Michael-type addition of 1 to alpha,beta-unsaturated Weinreb amide 83. Subsequent reaction with a Grignard reagent forms ketone 85. This ketone can also be synthesized in one step directly from 1 and alpha,beta-unsaturated ketone 84 using the same procedure. This ketone may be reduced with LAH, NaBH 4 or other reducing agents to form alcohol 86. Or else, ketone 85 can be reacted with an organolithium or Grignard reagents to form tertiary alcohol 87 . Or else, ester 80 can be directly reduced with LiBH 4 or LAH to yield primary alcohol 88.
Alcohols 86, 87 , and 88 can all be tosylated, mesylated, triflated, or converted to a halogen by methods discussed previously and displaced with an amine nucleophile such as azide, diphenylphosphoryl azide (with or without DEAD and Ph 3 P), phthalimide, etc. as discussed previously (and which are familiar to one skilled in the art) and after reduction (azide) or deprotection with hydrazine (phthalimide), for example, yield the corresponding amines. These can then be elaborated into the compounds of this invention as discussed previously. Ketone 85 can also be converted into imine 89 which can be reacted with a Grignard reagent or lithium reagent, etc., to form a protected amine 90 which can be deprotected and elaborated into the compounds of this invention as discussed previously. Some protecting groups include benzyl and substituted benzyl which can be removed by hydrogenation, and cyanoethyl, which can be removed with aqueous base, etc. It is to be understood that R 7-12 in Scheme 10 can be in their final form or in precursor form which can be elaborated into final form by procedures familiar to one skilled in the art.
Magnesium amides of amines have been used to add in a Michael-type manner to alpha,beta-unsaturated esters where the substituents at the beta position of the unsaturated ester are tied together to form a cyclopentane ring (for example, compound 79 where R 7 and R 8 are taken together to be —(CH 2 ) 4 —) (Kobayashi, K. et al., Bull Chem Soc Jpn, 1997, 70 (7), 1697-1699). Thus reaction of pyrrolidine or piperidine 1 with cycloalkylidine esters 79 as in Scheme 10 yields esters 80 where R 7 and R 8 are taken together to form a cycloalkyl ring. Subsequent elaboration yields compounds of this invention where R 7 and R 8 are taken together to form a cycloalkyl ring.
Compounds of structure 95a may also be synthesized from epoxyalcohols which are shown in Scheme 11. Allylic alcohol 91 can be epoxidized either stereoselectively using VO(acac) 2 catalyst (for a review, see Evans: Chem. Rev. 1993, 93, 1307) or enantioselectively (Sharpless: J. Am. Chem. Soc. 1987, 109, 5765) to epoxyalcohol 92. S N 2 displacement of the alcohol using zinc azide and triphenylphosphine (Yoshida, A. J. Org. Chem. 57, 1992, 1321-1322) or diphenylphosphoryl azide, DEAD, and triphenylphosphine (Saito, A. et al., Tet. Lett. 1997, 38 (22), 3955-3958) yields azidoalcohol 93. Hydrogenation over a Pd catalyst yields aminoalcohol 94. This can be protected in situ or in a subsequent step with BOC 2 O to put on a BOC protecting group, or with CBZ-Cl and base to put on a CBZ-group or other protecting groups. Alternatively, the amino group can be reacted with an isocyanate, an isothiocyanate, a carbamoyl chloride, or any reagent depicted in Scheme 1 to form 95 which can be alkylated with 1 to form the compounds of this invention.
Sometimes amine 1 might have to be activated with Lewis acids in order to open the epoxide ring (Fujiwara, M.; Imada, M.; Baba, A.; Matsuda, H.; Tetrahedron Lett 1989, 30, 739; Caron, M.; Sharpless, K. B.; J Org Chem 1985, 50, 1557) or 1 has to be deprotonated and used as a metal amide, for example the lithium amide (Gorzynski-Smith, J.; Synthesis 1984 (8), 629) or MgBr amide (Carre, M. C.; Houmounou, J. P.; Caubere, P.; Tetrahedron Lett 1985, 26, 3107) or aluminum amide (Overman, L. E.; Flippin, L. A.; Tetrahedron Lett 1981, 22, 195).
The quaternary salts (where R 4 is present as a substituent) of pyrrolidines and piperidines can be synthesized by simply reacting the amine with an alkylating agent, such as methyl iodide, methyl bromide, ethyl iodide, ethyl bromide, ethyl or methyl bromoacetate, bromoacetonitrile, allyl iodide, allylbromide, benzyl bromide, etc. in a suitable solvent such as THF, DMF, DMSO, etc. at room temperature to the reflux temperature of the solvent. Spiroquaternary salts can be synthesized in a similar manner, the only difference being that the alkylating agent is located intramolecularly as shown in Scheme 12. It is understood by one skilled in the art that functional groups might not be in their final form to permit cyclization to the quaternary ammonium salt and might have to be in precursor form or in protected form to be elaborated to their final form at a later stage. For example, the NR 1 (C=Z)NR 2 R 3 group on the rightmost phenyl ring of compound 104 might exist as a nitro group precursor for ease of manipulation during quaternary salt formation. Subsequent reduction and NR 1 (C=Z)NR 2 R 3 group formation yields product 105. The leaving groups represented by X in Scheme 12 may equal those represented in Scheme 1, but are not limited thereto. N-oxides of pyrrolidines and piperidines can be made by the procedure of L. W. Deady (Syn. Comm. 1977, 7, 509-514). This simply entails reacting the pyrrolidine or piperidine with MCPBA, for example, in an inert solvent such as methylene chloride.
Multisubstituted pyrrolidines and piperidines may be synthesized by the methods outlined in Scheme 13. Monoalkylation of 106 via an enolate using LDA or potassium hexamethyldisilazane, or converting 106 first to an enamine, or by using other bases, all of which can be done in THF, ether, dioxane, benzene, or an appropriate non-hydroxylic solvent at −78° C. to room temperature with an alkylating agent such as methyl iodide, benzyl bromide, etc. where X is as defined in Scheme 1, yields product 107. This product can subsequently undergo alkylation again under thermodynamic or kinetic conditions and afterwards, if need be, can undergo two more alkylations to produce tri- and tetrasubstituted analogs of 107. The thermodynamic or kinetic conditions yield regioselectively alkylated products (for a discussion on thermodynamic vs. kinetic alkylations see H. House Modern Synthetic Reactions, W. A. Benjamin, Inc. (Menlo Park, Calif.: 1972) chapter 9).
Subsequent Wittig olefination yields compound 108. Hydrogenation (asymmetric hydrogenation is an option here: Parshall, G. W. Homogeneous Catalysis, John Wiley and Sons, New York: 1980, pp. 43-45; Collman, J. P., Hegedus, L. S. Principles and Applications of Organotransition Metal Chemistry, University Science Books, Mill Valley, Calif., 1980, pp. 341-348) yields pyrrolidine or piperidine 109 which can be resolved into its relative and/or absolute isomers at this stage or later on in the synthesis either by crystallization, chromatographic techniques, or other methods familiar to one skilled in the art. The amine 109 an then be elaborated into the compounds of this invention by methods discussed previously (Scheme 1). The carbonyl-containing intermediate 107 in Scheme 13 can also be reduced to the methylene analog via a Wolff-Kishner reduction and modifications thereof, or by other methods familiar to one skilled in the art. The carbonyl group can also be reduced to an OH group, which can undergo all of the reactions described in Scheme 9 to synthesize the R6 groups. This piperidine or pyrrolidine can be deprotected and elaborated to the compounds of this invention by methods discussed earlier. Thus, mono-, di-, tri-, or tetraalkylated carbonyl-containing pyrrolidines or piperidines can be synthesized, which in turn can be reduced to the corresponding —CH 2 — analogs employing the Wolff-Kishner reduction or other methods.
Another method for synthesizing gem-substituted pyrrolidines and piperidines is shown in Scheme 14. It is understood by one skilled in the art that some of the steps in this scheme can be rearranged. It is also understood that gem-disubstitution is only shown at only one position on the piperidine ring and that similar transformations may be performed on other carbon atoms as well, both for piperidine and pyrrolidine. Thus, 3-carboethoxypiperidine 110 may be BOC-protected and alkylated employing a base such as LDA, KHMDS, LHDMS, etc., in THF, ether, dioxane, etc. at −78° C. to room temperature, and an alkylating agent R 6 X where X is a halide (halide=Cl, Br, I), mesylate, tosylate or triflate, to yield 112. Reduction using DIBAL, for example, and if necessary followed by oxidation such as a Swern oxidation (S. L. Huang, K. Omura, D. Swern J. Org. Chem. 1976, 41, 3329-32) yields aldehyde 113. Wittig olefination (114) followed by deprotection yields 115 which may be elaborated as described previously into the compounds of this invention. Reduction of the Wittig adduct 114 yields 116 which may be deprotected to yield 117 which may be in turn elaborated as described previously into the compounds of this invention. Reaction of aldehyde 113 with an alkyllithium or Grignard reagent yields alcohol 118 which may be reduced catalytically or with Et3SiH/TFA (J. Org. Chem. 1969, 34, 4; J. Org. Chem. 1987, 52, 2226) if R 5 * (R 5 *═R 5 or a precursor thereof) is aromatic to yield 119. If R 5 * is not aromatic, then the OH may be reduced by the method of Barton (Barton, D. H. R.; Jaszberenyi, J. C. Tet. Lett. 1989, 30, 2619 and other references therein). Once tosylated, the alcohol can also be displaced with dialkyllithium cuprates (not shown) (Hanessian, S.; Thavonekham, B.; DeHoff, B.; J Org. Chem. 1989, 54, 5831). Deprotection if necessary yields 120 which may be elaborated as described previously into the compounds of this invention.
A method for the alkylation of alkyl groups, arylalkyl groups, allylic groups, propargylic groups, etc., and a variety of other electrophiles onto the pyrrolidinyl and/or piperidinyl alpha-carbons (alpha to the ring nitrogen atom) is represented by the work of Peter Beak, et al. as shown in Scheme 15. It is understood by one skilled in the art that the R 5 and R 13 groups are either in their precursor, protected, or final form. Only one R 5 group is shown to be substituted on piperidine/pyrrolidine 121. However it is understood by one skilled in the art that additional functionality may be present on the ring in either precursor, protected, or final form. Thus lithiation with an alkyllithium reagent such as n-BuLi or s-BuLi as shown, followed by quenching with an electrophilic species such as R 5 X or R 13 X where X is as defined in Scheme 1 and R 5 and R 13 are in their precursor, protected, or final form, yields monoalkylated piperidine/pyrrolidine 122. This alkylation may occur either stereoselectively (P. Beak and W. K. Lee J. Org. Chem. 1990, 55, 2578-2580) or enantioselectively if sparteine is included as a source of chirality (P. Beak, et al., J. Am. Chem. Soc. 1994, 116, 3231-3239). The alkylation process may be repeated up to three more times as shown in Scheme 15 to result in di-, tri-, and tetrasubstitution at the alpha-positions.
Compounds where R 9 and R 10 form a cyclic 3,4,5,6, or 7-membered ring can be synthesized by the methods disclosed in Scheme 16. These same methods may also be used to synthesize gem-disubstituted compounds in which R 9 can be different from R 10 by step-wise alkylation of the malonate derivative. Of course, this scheme may be used to synthesize compounds where R 10 ═H also. For example, a cyclohexyl-fused malonate may be synthesized by Michael addition and alkylation of I(CH2) 4 CH═CCO 2 Me with dimethyl malonate employing NaH/DMF (Desmaele, D.; Louvet, J.-M.; Tet Lett 1994, 35 (16), 2549-2552) or by a double Michael addition (Reddy, D. B., et al., Org. Prep. Proced. Int. 24 (1992) 1, 21 -26) (Downes, A. M.; Gill, N. S.; Lions, F.; J Am Chem or by an alkylation followed by a second intromolecular alkylation employing an iodoaldehyde (Suami, T.; Tadano, K.; Kameda, Y.; Iimura, Y.; Chem Lett 1984, 1919), or by an alkylation followed by a second intramolecular alkylation employing an alkyl dihalide (Kohnz, H.; Dull, B.; Mullen, K.; Angew Chem 1989, 101 (10), 1375), etc.
Subsequent monosaponification (Pallai, P. V., Richman, S., Struthers, R. S., Goodman, M. Int. J. Peptide Protein Res. 1983, 21, 84-92; M. Goodman Int. J. Peptide Protein Res. 19831, 17, 72-88), standard coupling with pyrrolidine/piperidine 1 yields 128. Reduction with borane yields 129 followed by reduction with LAH yields 130 which can be then converted to amine 131 and then to the compounds of this invention by procedures as discussed previously. Ester 129 can also be converted to a Weinreb amide and elaborated to the compounds of this invention as described in Scheme 10 for ester 80 which would introduce substituents R 11 and R 12 .
Scheme 17 describes another method for the synthesis of compounds where R 9 and R 10 are taken together to form cycloalkyl groups. Aminoalcohols 132 are found in the literature (CAS Registry Nos. for n=0,1,2,3, respectively: 45434-02-4, 2041-56-7, 2239-31-8, 2041-57-8). They can easily be protected, as with a BOC group (or CBZ, or any other compatible protecting group) by known procedures familiar to one skilled in the art to yield alcohols 133. The alcohols can then be activated either by conversion to a halide or to a mesylate, tosylate or triflate by methods familiar to one skilled in the art and as discussed previously, and then alkylated with pyrrolidine/piperidine 1 by the conditions described in Scheme 1 to yield 135. Subsequent deprotection yields amine 136 which can be elaborated to the compounds of this invention as described previously. Of course, alcohol 133 can be oxidized to the aldehyde and then reacted with R 7or8 MgBr or R 7or8 Li with or without CeCl 3 to yield the corresponding alcohol 133 where instead of —CH 2 OH, we would have —CHR 7or8 OH. This oxidation-1,2-addition sequence may be repeated to yield a tertiary alcohol. The alcohol may then be tosylated, mesylated, triflated, or converted to Cl, Br, or I by procedures familiar to one skilled in the art to yield 134 and then displaced with pyrrolidine/piperidine 1 to yield 135. Subsequent deprotection yields 136 which may undergo elaboration to the compounds of this invention as discussed previously.
A method to introduce cycloalkyl groups at R 11 R 12 is shown in Scheme 18. Protection of the nitrogen of compounds 137 which are commercially available yields 138 (the protecting group may be BOC, CBZ, or any other compatible protecting group) by procedures familiar to one skilled in the art. Esterification by any one of a number procedures familiar to one skilled in the art (for example A. Hassner and V. Alexanian, Tet. Lett, 1978, 46, 4475-8) followed by reduction with DIBAL (or alternatively reduction to the alcohol with, for example, LiBH 4 , followed by Swern oxidation (op. cit.)) yields aldehyde 139. One carbon homologation via the Wittig reaction followed by hydrolysis of the vinyl ether yields aldehyde 141. Reductive amination (Abdel-Magid, A. F., et al. Tet. Lett. 1990, 31, (39) 5595-5598) yields 142 followed by deprotection yields amine 143 which can be elaborated to the compounds of this invention by the methods previously discussed. Of course, aldehyde 139 can be reacted with R 9or10 MgBr or R 9or10 Li with or without CeCl 3 to yield an alcohol which can be oxidized to a ketone. Wittig one-carbon homologation on this ketone as described above followed by hydrolysis yields 141 where the —CH 2 CHO is substituted with one R 9or10 group (—CHR 9or10 CHO).
Aldehyde 141 (—CH 2 CHO) or its monosubstituted analog synthesized above (—CHR 9or10 CHO) can undergo alkylation with R 9or10 X where X is as defined in Scheme 1 to yield compound 141 containing one or both of the R 9 and R 10 substituents alpha to the aldehyde group. Alkylation can be performed using LDA or lithium bistrimethylsilyl amide amongst other bases in an inert solvent such as ether, THF, etc., at −78° C. to room temperature. Aldehyde 141 (—CH 2 CHO) or its substituted analogs synthesized above (i.e., —CHR 9 R 10 CHO) can undergo reductive amination with 1 and subsequent elaboration to the compounds of this invention. Aldehyde 141 (—CH 2 CHO) or its substituted analogs synthesized above (i.e., —CHR 9 R 10 CHO) can also undergo 1,2-addition with R 7or8 MgBr or R 7or8 Li to yield the corresponding alcohol —CH 2 CHR 7or8 OH or —CHR 9 R 10 CHR 7or8 OH. The alcohol may then be tosylated, mesylated, triflated, or converted to Cl, Br, or I by procedures familiar to one skilled in the art and displaced with pyrrolidine/piperidine 1 to yield, after subsequent deprotection and elaboration, the compounds of this invention. Or else alcohol —CH 2 CHR 7or8 OH or —CR 9 R 10 CHR 7or8 OH can be oxidized (i.e., Swern, op. cit.) to the ketone and reductively aminated with 1 and subsequently elaborated to the compounds of this invention. Or else alcohol —CH 2 CHR 7or8 OH or —CR 9 R 10 CHR 7or8 OH can be oxidized (i.e., Swern, op. cit.) to the ketone and reacted once more with R 7or8 MgBr or R 7or8 Li to yield the corresponding alcohol —CH 2 CR 7 R 8 OH or —CR 9 R 10 CR 7 R 8 OH. If the ketone enolizes easily, CeCl 3 may be used together with the Grignard or lithium reagent. The alcohol can again be tosylated, mesylated, triflated, or converted to Cl, Br, or I by procedures familiar to one skilled in the art and displaced with pyrrolidine/piperidine 1 to yield, after subsequent deprotection and elaboration, the compounds of this invention. Thus each one of the R 7 , R 8 , R 9 , and R 10 groups may be introduced into compounds 141, 142 and 143 and and, of course, in the compounds of this invention, by the methods discussed above.
A method for the synthesis of N-substituted heterocycles at R 5 is shown in Scheme 19. The heterocycle can be deprotonated with NaH or by other bases familiar to one skilled in the art, in a solvent such as DMF, THF, or another appropriate non-hydroxylic solvent and reacted with piperidine or pyrrolidine 143 at room temperature to the reflux temperature of the solvent. Deprotection and elaboration as described before yields compounds where R 5 contains an N-substituted heterocycle. If the nitrogen atom of the heterocycle is sufficiently nucleophilic, then an acid scavenger, such as K 2 CO 3 , KHCO 3 , Na 2 CO 3 , NaHCO 3 , amongst others, can be used in place of NaH, employing THF, DMF, or methyl ethyl ketone as solvents. In this case hydroxylic solvents may be used as well, such as methanol, ethanol, etc. from room temperature to the reflux temperature of the solvent. Compound 143 as well as its other positional isomers are available, for example, from commercially available 4-hydroxymethylpiperidine, 2-, 3-, and 4-carboethoxypiperidine, L- or D-proline ethyl ester, or from methyl 1-benzyl-5-oxo-3-pyrrolidinecarboxylate by methods familiar to one skilled in the art and as discussed previously in this application.
A method for the synthesis of C-substituted heterocycles at R 5 is shown in Scheme 20. Many heterocycles such as the ones shown in Scheme 20, but not limited thereto, can be metallated with strong bases such as LDA, n-BuLi, sec-BuLi, t-BuLi, etc. to yield the corresponding anionic species. These anions may also be generated via halogen-metal exchange employing n-BuLi, or other alkyllithium reagents. These reactions may be performed in THF, ether, dioxane, DME, benzene, etc. at −78° C. to room temperature.
or reviews of these metallations and halogen-metal exchange reactions see Organometallics in Organic Synthesis, FMC Corp., Lithium Division, 1993, pp. 17-39; Lithium Link, FMC Corp., Spring 1993, pp. 2-17; n-Butyllithium in Organic Synthesis, Lithium Corp. of America, 1982, pp. 8-16; G. Heinisch, T. Langer, P. Lukavsky, J. Het. Chem. 1997, 34, 17-19. The anions can then be quenched with electrophile 143 or its positional isomers to yield the corresponding C-alkylated heterocyclic pyrrolidine or piperidine 145.
Another method for the synthesis of C-substituted heterocyclic-methylpyrrolidines or piperidines is shown in Scheme 21. The protected aldehyde 146 is reacted with the anion of the heterocycle (its generation as described previously) at −78° C. to room temperature with or without CeCl 3 in an inert solvent such as THF, ether, dioxane, DME, benzene, etc. to yield carbinol 147. Catalytic hydrogenation of the alcohol yields the corresponding methylene compound 145. Other reduction methods include Et 3 SiH/TFA (J. Org. Chem. 1969, 34, 4; J. Org. Chem. 1987, 52, 2226) amongst others familiar to one skilled in the art. It is understood by one skilled in the art that the aldehyde group can be located in other positions instead of, for example, the 4-position of piperidine in compound 146 as depicted in Scheme 21. It is to be understood that other heterocycles may also be used besides the ones shown in Scheme 20 and 21.
The anions of the methyl-substituted heterocycles may also be reacted with a BOC-protected piperidone or pyrrolidone (148) to yield alcohols 149 as shown in Scheme 22 (see above reviews on metallations for references). These alcohols may be reduced using PtO 2 and TFA (P. E. Peterson and C. Casey, J. Org. Chem. 1964, 29, 2325-9) to yield piperidines and pyrrolidines 150. These can subsequently be taken on to the compounds of this invention as described previously. It is understood by one skilled in the art that the carbonyl group can be located in other positions instead of, for example, the 4-position of piperidine in compound 148 as depicted in Scheme 22. It is to be understood that other heterocycles may also be used besides the ones shown in Scheme 22.
One may also react aryl (phenyl, naphthyl, etc.) anions, generated either by halogen-metal exchange or by ortho-directed metallation (Snieckus, V. Chem. Rev. 1990, 90, 879-933) using n- or s- or t-BuLi in a non-hydroxylic solvent such as THF, ether, etc., with or without TMEDA and allow them to react with compounds 143, 146, and 148 with subsequent elaboration to yield the compounds of this invention by the methods depicted in Schemes 19-22.
Another method for the preparation of C-substituted heterocycles is shown in Scheme 23. Protected piperidone 148 undergoes a Wittig reaction with heterocyclic phosphorous ylides to yield 151. Hydrogenation over a noble metal catalyst such as Pd in an alcoholic solvent or with an optically active transition metal catalyst (see asymmetric hydrogenation references of Parshall and Coleman, op. cit.) yields 152 which can be further elaborated into the compounds of this invention by the procedures described previously. It will be appreciated by one skilled in the art that the carbonyl group can be located in other positions instead of, for example, the 4-position of piperidine in compound 148 as depicted in Scheme 23. It is to be understood that other heterocycles may also be used besides the ones shown in Scheme 23.
Syntheses of amines 9, 10, and the amines which are precursors to isocyanates or isothiocyanates 5 will now be discussed. For example, 3-nitrobenzeneboronic acid (153: Scheme 24) is commerically available and can undergo Suzuki couplings (Suzuki, A. Pure Appl. Chem. 1991, 63, 419) with a wide variety of substituted iodo- or bromo aryls (aryls such as phenyl, naphthalene, etc.), heterocycles, alkyls, akenyls (Moreno-manas, M., et al., J. Org. Chem., 1995, 60, 2396), or alkynes. It can also undergo coupling with triflates of aryls, heterocycles, etc. (Fu, J.-m, Snieckus, V. Tet. Lett. 1990, 31, 1665-1668). Both of the above reactions can also undergo carbonyl insertion in the presence of an atmosphere of carbon monoxide (Ishiyama, et al., Tet. Lett. 1993, 34, 7595). These nitro-containing compounds (155 and 157) can then be reduced to the corresponding amines either via catalytic hydrogenation, or via a number of chemical methods such as Zn/CaCl 2 (Sawicki, E. J Org Chem 1956, 21). The carbonyl insertion compounds (158) can also undergo reduction of the carbonyl group to either the CHOH or CH2 linkages by methods already discussed (NaBH 4 or Et 3 SiH, TFA, etc.). These amines can then be converted to isocyanate 5 via the following methods (Nowakowski, J. J Prakt Chem/Chem-Ztg 1996, 338 (7), 667-671; Knoelker, H.-J.et al., Angew Chem 1995, 107 (22), 2746-2749; Nowick, J. S.et al., J Org Chem 1996, 61 (11), 3929-3934; Staab, H. A.; Benz, W.; Angew Chem 1961, 73); to isothiocyanate 5 via the following methods (Strekowski L.et al., J Heterocycl Chem 1996, 33 (6), 1685-1688; Kutschy, Pet al., Synlett 1997, (3), 289-290); to carbamoyl chloride 11 (after 156 or 158 is reductively aminated with an R 2 group) (Hintze, F.; Hoppe, D.; Synthesis (1992) 12, 1216-1218); to thiocarbamoyl chloride 11 (after 156 or 158 is reductively aminated with an R 2 group) (Ried, W.; Hillenbrand, H.; Oertel, G.; Justus Liebigs Ann Chem 1954, 590); or just used as 9, or 10 (after 156 or 158 is reductively aminated with an R 2 group), in synthesizing the compounds of this invention by the methods depicted in Scheme 1.
Likewise, protected aminobromobenzenes or triflates or protected aminobromoheterocycles or triflates 159 (Scheme 25) may undergo Suzuki-type couplings with arylboronic acids or heterocyclic boronic acids (160). These same bromides or triflates 159 may also undergo Stille-type coupling (Echavarren, A. M., Stille, J. K. J. Am. Chem. Soc., 1987, 109, 5478-5486) with aryl, vinyl, or heterocyclic stannanes 163. Bromides or triflates 159 may also undergo Negishi-type coupling with other aryl or heterocyclic bromides 164 (Negishi E. Accts. Chem. Res. 1982, 15, 340; M. Sletzinger, et al., Tet. Lett. 1985, 26, 2951). Deprotection of the amino group yields an amine with can be coupled to make a urea and other linkers containing Z as described above and for Scheme 1. Amino protecting groups include phthalimide, 2,4-dimethyl pyrrole (S. P. Breukelman, et al. J. Chem. Soc. Perkin Trans. I, 1984, 2801); N-1,1,4,4-Tetramethyldisilyl-azacyclopentane (STABASE) (S. Djuric, J. Venit, and P. Magnus Tet. Lett 1981, 22, 1787) and others familiar to one skilled in the art.
Compounds where R 7 and R 8 are taken together to form ═NR 8b can be synthesized by the methods in Scheme 25a. Reacting 1 with nitrile a with CuCl catalysis forms amidine b where R 8b is H (Rousselet, G.; Capdevielle, P.; Maumy, M.; Tetrahedron Lett. 1993, 34 (40), 6395-6398). Note that the urea portion may be in final form or in precursor form (for example, a protected nitrogen atom; P=protecting group such as STABASE, bis-BOC, etc., as was discussed previously) which may be subsequently elaborated into the compounds of this invention. Compounds b may be also synthesized by reacting iminoyl chloride c with pyrrolidine/piperidine 1 to yield b where R 8b is not H (Povazanec, F., et al., J. J. Heterocycl. Chem., 1992, 29, 6, 1507-1512). Iminoyl chlorides are readily available from the corresponding amide via PCl 5 or CCl 4 /PPh 3 (Duncia, J. V. et al., J. Org. Chem., 1991, 56, 2395-2400). Again, the urea portion may be in final form or in precursor form.
Many amines are commercially available and can be used as 9, 10, or used as precursors to isocyanates or isothiocyanates 5. There are numerous methods for the synthesis of non-commercially available amines familiar to one skilled in the art. For example, aldehydes and ketones may be converted to their O-benzyl oximes and then reduced with LAH to form an amine (Yamazaki, S.; Ukaji, Y.; Navasaka, K.; Bull Chem Soc Jpn 1986, 59, 525). Ketones and trifluoromethylketones undergo reductive amination in the presence of TiCl 4 followed by NaCNBH 4 to yield amines (Barney, C. L., Huber, E. W., McCarthy, J. R. Tet. Lett. 1990, 31, 5547-5550). Aldehydes and ketones undergo reductive amination with Na(AcO) 3 BH as mentioned previously to yield amines (Abdel-Magid, A. F., et al. Tet. Lett. 1990, 31, (39) 5595-5598). Amines may also be synthesized from aromatic and heterocyclic OH groups (for example, phenols) via the Smiles rearrangement (Weidner, J. J., Peet, N. P. J. Het. Chem., 1997, 34, 1857-1860). Azide and nitrile displacements of halides, tosylates, mesylates, triflates, etc. followed by LAH or other types or reduction methods yield amines. Sodium diformyl amide (Yinglin, H., Hongwen, H. Synthesis 1989 122), potassium phthalimide, and bis-BOC-amine anion can all displace halides, tosylates, mesylates, etc., followed by standard deprotection methods to yield amines, procedures which are familiar to one skilled in the art. Other methods to synthesize more elaborate amines involve the Pictet-Spengler reaction, imine/immonium ion Diels-Alder reaction (Larsen, S. D.; Grieco, P. A. J. Am. Chem. Soc. 1985, 107, 1768-69; Grieco, P. A., et al., J. Org. Chem. 1988, 53, 3658-3662; Cabral, J. Laszlo, P. Tet. Lett. 1989, 30, 7237-7238; amide reduction (with LAH or diborane, for example), organometallic addition to imines (Bocoum, A. et al., J. Chem. Soc. Chem. Comm. 1993, 1542-4) and others all of which are familiar to one skilled in the art.
Compounds containing an alcohol side-chain alpha to the nitrogen of the piperidine/pyrrolidine ring can be synthesized as shown in Scheme 25b. Only the piperidine case is exemplified, and it is to be understood by one skilled in the art that the alpha-substituted pyrrolidines may be synthesized by a similar route. It is also understood that appropriate substituents may be present on the piperidine/pyrrolidine ring. A 4-benzylpiperidine 196 is protected with a BOC group. The BOC-piperidine 197 is then metallated under conditions similar to those Beak, et al. (P. Beak and W.-K. Lee, J. Org. Chem. 1990, 55, 2578-2580, and references therein) and quenched with an aldehyde to yield alcohol 198. The metallation may also be done enantioselectively using sparteine (P. Beak, S. T. Kerrick, S. Wu, J. Chu J. Am. Chem. Soc. 1994, 116, 3231-3239). This alcohol can be deprotonated with NaH and cyclized to carbamate 198a which permits structural assignments of the erythro and threo isomers. Deprotection with base yields aminoalcohol 199. Subsequent N-alkylation yields phthalimidoalkylpiperidine 201. It is to be understood that the alkyl chain does not necessarily have to be n-propyl, but that n-propyl was chosen for demonstration purposes only. Deprotection of the phthalimido group with hydrazine yields amine 202. Finally, reaction with an isocyanate or via any of the previously described conditions described in Scheme 1 yields urea 203. If an isocyanate is used, the isocyanate can add twice to yield urea-carbamate 204.
Compounds where Z=N—CN, CHNO 2 , and C(CN) 2 can be synthesized by the methods shown in Scheme 25c. Thus amine 208 reacts with malononitrile 207 neat or in an inert solvent at room temperature to the reflux temperature of the solvent, or at the melting point of the solid/solid mixture, to yield malononitrile 206. This in turn can undergo reaction with amine 205 under similar conditions stated just above to yield molononitrile 209. Likewise, a similar reaction sequence may be used to make 212 and 215 [for Z=C(CN) 2 ], see for example P. Traxler, et al., J. Med. Chem. (1997), 40, 3601-3616; for Z=N—CN, see K. S. Atwal, J. Med. Chem. (1998) 41, 271; for Z=CHNO 2 , see J. M. Hoffman, et al., J. Med. Chem. (1983) 26, 140-144).

Example 3
Part A: Preparation of 1-(t-Butoxycarbonyl)-3-piperidone
To a deep yellow solution of 1-benzyl-3-piperidone hydrochloride (3.00 g, 1.33 mmol, 1 equiv) in methanol (100 mL) was added 10 wt. % (dry basis) palladium on activated carbon (600 mg) under a stream of nitrogen. The resulting black suspension was deoxygenated by alternate evacuation and flushing with nitrogen (3×) followed by alternate evacuation and flushing with hydrogen (3×). The reaction suspension was then shaken vigorously under a hydrogen atmosphere of 55 psi. After 12 hours, gravity filtration of the supsension and concentration of the resulting filtrate in vacuo yielded crude 3-piperidone as a viscous light green oil. The oil was immediately treated with tetrahydrofuran (150 mL) and di-t-butyldicarbonate (4.73 g, 21.7 mmol, 0.98 equiv). Upon addition of saturated aqueous sodium bicarbonate (25 mL), the oil completely dissolved to give a light yellow suspension. After stirring the suspension vigorously for 2 hours, the now white suspension was poured into aqueous hydrogen chloride (1N, 100 mL), and the layers were separated. The aqueous layer was extracted with ethyl acetate (3×70 mL), and the combined organic layers were washed with saturated aqueous sodium chloride (50 mL), dried over sodium sulfate, and filtered.

The compounds of the present invention in which E contains ring A can be prepared in a number of ways well known to one skilled in the art of organic synthesis. As shown in Scheme 26, 4-benzyl piperidine is N-alkylated with an alkylating agent, such as 165 (2-nitro-benzyl bromide (X═Br, R 14 ═H), Scheme 26) to give the N-benzyl compound 166. The nitro group of 166 is then reduced using catalytic hydrogenation to give the corresponding aniline 167. The aniline can be converted to the carbamate 168 using chloro-phenyl formate. The carbamate 168 can then be reacted with various amines to give the urea 169. Alternatively, the aniline 167 can be reacted with the appropriate isocyanates to give the urea 169 directly. The saturated ring analogs can also be used. For example, 4-benzyl piperidine can be alkylated with the urea mesylate 185 (Scheme 30) to give corresponding cyclohexyl derivative 186.
As shown in Scheme 27, 4-benzyl piperidine can also be N-alkylated with the phenacyl bromide 170 to give the nitro ketone 171. The nitro group of 171 is then reduced using catalytic hydrogenation to give the corresponding aniline 172. The aniline 172 can be reacted with the appropriate isocyanates to give the ketone urea 173. The ketone of 173 can be reduced with NaBH 4 to give the alcohol 174.
Alternatively, the epoxide 175 (R 14 =H) can be opened with the 4-benzyl piperidine to give the corresponding nitro benzyl alcohol which is hydrogenated to give the aniline alcohol 176. The aniline 176 may be treated with various isocyanates to give the urea alcohols 174.
The 4-benzyl piperidine can also be N-alkylated with 3-cyanobenzyl bromide (177, Scheme 28) to give the cyano analog 178. The cyano group is reduced using Raney nickel to give the corresponding benzyl amine 179. Treatment of 179 with isocyanates gives the urea 180.
As shown in Scheme 29, treatment of 3-cyano aniline with phenylisocyanate gives the urea 182. The cyano group of 182 is converted to the imidate 183 by HCl/ethanol. Reaction with 4-benzyl piperidine in ethanol then gives the amidine 184.
The saturated ring analogs can also be synthesized using analogous procedures as outlined in Schemes 30 and 31. For example, 4-benzyl piperidine can be alkylated with the urea mesylate 185 (Scheme 29) to give corresponding cyclohexyl derivative 186. Alternatively, starting with the enantiomerically pure amino alcohol 187 [J. Am. Chem. Soc. 1996, 118, 5502-5503 and references therein] one can protect the nitrogen to give the N-Cbz alcohol 188. Swern oxidation of the alcohol gives the aldehyde 189. Reductive amination with piperidine analogs gives the cyclohexyl methyl-1-piperidinyl analogue 190. The Cbz group is removed by catalytic hydrogenation to give the free amine 191, which is treated with a phenylisocyanate to give the desired urea analogue 192. Several examples using these synthetic methods are listed in Table 3a and Table 3.1.
The following examples were synthesized using the methods outlined in Schemes 26-31a. These examples are meant to be illustrative of the present invention, and are not to be limiting thereof.

Soc. 1996, 118, 5502-5503] (9.5 g, 73.8 mmol) in CH 2 Cl 2 (200 mL) is added 200 ml of an aqueous solution of Na 2 CO 3 (15 g, 141 mmol). While stirring, benzyl chloroformate (12.6 g, 73.8 mmol) is added slowly and the mixture is stirred at room temperature for 1 h. The organic layer is separated and washed with water and brine. The organic solvent is removed on a rotary evaporator to give a white solid. The solid is recrystallized from hexane to give 16.3 g (62 mmol) of the alcohol 188 (Scheme 31a)as a white solid. 1 H NMR (300 MHz, CDCl 3 ) δ 7.40-7.29 (m, 5 H), 5.11 (s, 2 H), 4.71 (bd, 1 H), 3.76-3.71 (m, 1 H), 3.53-3.28 (m, 3 H), 2.00-1.95 (m, 1 H), 1.90-1.09 (m, 8 H). MS AP + (M+H) + =264.3 (100 %)
Step b: A solution of DMSO (36 g, 430 mmol) in CH 2 Cl 2 (200 mL) is cooled to −78° C. To this solution is added drop-wise oxalyl chloride (27.41 g, 216 mmol) and the resulting solution is stirred for an additional 10 min. A solution of alcohol 188 (38 g, 144 mmol) in CH 2 Cl 2 (150 ml) is added via an addition funnel and stirred for 10 min. Then, Et 3 N (58 g, 570 mmol) is added and the solution is stirred for 20 min and the ice bath removed and stirred for an additional 30 min. The solution is diluted with water and the organic layer separated and washed with water, 1 N HCl, and brine. The organic layer is dried over Na 2 SO 4 , filtered, and concentrated to give 38 g of aldehyde 189 as a white solid. The solid is recrystallized from hexane to give 19.7 grams of a first crop of aldehyde 189 as white needles. A second crop gave an additional 11 grams. 1 H NMR (300 MHz, CDCl 3 ) δ 9.59 (d, 3.6 Hz, 1 H), 7.38-7.28 (m, 5 H), 5.07 (m, 2 H), 4.69 (m, 1 H), 3.84 (m, 21 H), 2.19-2.11 (m,1 H), 2.09-2.01 (m, 1 H), 1.86-1.75 (m, 3 H), 1.54-1.17 (m, 4 H).
Step c: A solution of aldehyde 189 (19.6 g, 75 mmol) and (3S)-3-(4-fluorophenylmethyl)piperidine (14.5 g, 75 mmol) in dichloroethane (400 ml) was treated with Na(OAc) 3 BH (32 g, 152 mmol) and stirred overnight at room temperature. The resulting solution was poured slowly into a stirred mixture of ice/water/1 N NaOH and stirred for 20 min. The organic layer was separated and washed water, and brine. The solution was dried over MgSO 4 and the organic solvent was removed under vacuum and the residue chromatographed on basic alumina (50% EtOAc/hexane) to give 32.1 g (73 mmol) of amine 193 as mixture of (15%)cis and trans isomers. 1 H NMR (300 MHz, CDCl 3 ) δ 7.79 (bs, 1 H), 7.38-7.29 (m, 5 H), 6.95-6.84 (m, 4 H), 5.08 (m, 2 H), 3.71 (m, 1 H, cis isomer ), 3.06 (m, 1 H, trans isomer), 2.80 (m, 1 H), 2.55-2.36 (m, 2 H), 2.30 (dd, J=9 Hz, J=13 Hz, 1 H, trans isomer), 2.05 (dd, J=2 Hz, J=13 Hz , 1 H, trans isomer), 1.81-0.90 (m, 16 H).
Step d: A solution of 193 (32 g, 73 mmol) in MeOH was treated with 8 g of 10% Pd/C and hydrogenated at 50 psi overnight in a Parr apparatus. The mixture was filtered and the filtrate concentrated on a rotary evaporator to give 20 g (65 mmol) of the amine 194, which was used without further purification.
Step e: A solution of amine 194 (10 g, 32.8 mmol) in THF is treated with 3-acetylyphenyl isocyanate (5.3 g, 32.8 mmol) and the mixture is stirred for 30 min. The solvent is removed on a rotary evaporator and the residue is chromatographed on silica gel (0.5:4.5:95 NH 4 OH/MeOH/CH 2 Cl 2 ) to give 11 g of urea 195 (Example 415) as a solid. Also obtained 2 g of cis isomer (Example 416a). The urea Example 415 was further purified by a second chromatography on silica gel (40:60:1 EtAc/Hex/TEA) and final recrystallization from ether to give crystalline solid. mp 115-117° C., [α] D 25 =+16.80° (CH 3 OH, c=0.23 g/dL). 1 H NMR (300 MHz, CDCl 3 ) δ 7.86 (m, 1 H), 7.78 (bs, 1 H), 7.68-7.64 (m, 1 H), 7.62-7.59(m, 1 H), 7.38 (t, J=8 Hz, 1 H), 6.95-6.90 (m, 2 H), 6.79-6.72 (m, 2 H), 6.25 (s, 1 H), 3.21 (dt, J=3 Hz, 11 Hz, 1 H), 3.00-2.97 (m, 1 H), 2.66-2.56 (m, 1 H), 2.61 (s, 3 H), 2.44-2.32 (m, 4 H), 2.06 (dd, J=2 Hz, J=13 Hz, 1 H), 1.80-0.86 (m, 15 H).
