Description
发明领域
本发明涉及某些苯并咪唑-2-基吡啶,含有它们的药物组合物,和使用它们治疗由组胺H4受体活性介导的疾病状态、病症和状况的方法。
发明背景
组胺H4受体(H4R)是最近鉴定的组胺受体(文献综述参见:Fung-Leung,W.-P.等人,Curr.Opin.Invest.Drugs 2004,5(11),1174-1183;de Esch,I.J.P.等人,Trends Pharmacol.Sci.2005,26(9),462-469)。该受体在骨髓和脾脏中被发现,并且其表达在嗜酸性细胞、嗜碱性白细胞、肥大细胞(Liu,C.等人,Mol.Pharmacol.2001,59(3),420-426;Morse,K.L.等人,J.Pharmacol.Exp.Ther.2001,296(3),1058-1066;Hofstra,C.L.等人,J.Pharmacol.Exp.Ther.2003,305(3),1212-1221;Lippert,U.等人,J.Invest.Dermatol.2004,123(1),116-123;Voehringer,D.等人,Immunity 2004,20(3),267-277)、CD8+T细胞(Gantner,F.等人,J.Pharmacol.Exp.Ther.2002,303(1),300-307)、树状细胞和类风湿性关节炎患者的人类滑膜细胞(Ikawa,Y.等人,Biol.Pharm.Bull.2005,28(10),2016-2018)上。然而,在嗜中性白细胞和单核细胞中的表达并没有得到充分确定(Ling,P.等人,Br.J.Pharmacol.2004,142(1),161-171)。受体表达至少部分受各种炎性刺激的控制(Coge,F.等人,Biochem.Biophys.Res.Commun.2001,284(2),301-309;Morse等人,2001),由此支持该H4受体活化影响炎性反应。由于它在免疫活性细胞上优先表达,因此在免疫反应期间H4受体与组胺的调节功能紧密相关。
在免疫学和自身免疫疾病环境中,组胺的生物活性与变应性反应和它的有害作用(比如炎症)紧密相关。引起炎性反应的事件包括物理刺激(包括创伤)、化学刺激、感染和异物侵入。炎性反应的特征在于疼痛、升高的温度、发红、肿胀、降低的功能或者其组合。
肥大细胞脱粒作用(胞吐作用)释放组胺并且引起初始特征可为组胺-调节的水疱和光斑反应的炎性响应。多种免疫学刺激(例如变应素或者抗体)和非免疫学(例如,化学)刺激都可以导致肥大细胞的活化、补充和去粒化。肥大细胞的活化引发变应性的炎性响应,这进而导致进一步促进炎性响应的其它效应细胞的补充。已经表明,组胺诱发小鼠肥大细胞的趋化性(Hofstra等人,2003)。使用来源于H4受体剔除小鼠的肥大细胞,并不产生趋化性。此外,所述响应被H4-特异性拮抗剂阻断,而不是被H1、H2或者H3受体拮抗剂阻断(Hofstra等人,2003;Thurmond,R.L.等人,J.Pharmacol.Exp.Ther.2004,309(1),404-413)。肥大细胞在体内向组胺的迁移还被研究和表明是H4受体依赖的(Thurmond等人,2004)。肥大细胞的迁移可能在过敏性鼻炎和变应性反应中起作用,发现其中肥大细胞的数量产生了增长(Kirby,J.G.等人,Am.Rev.Respir.Dis.1987,136(2),379-383;Crimi,E.等人,Am.Rev.Respir.Dis.1991,144(6),1282-1286;Amin,K.等人,Am.J.Resp.Crit.Care Med.2000,162(6),2295-2301;Gauvreau,G.M.等人,Am.J.Resp.Crit.Care Med.2000,161(5),1473-1478;Kassel,O.等人,Clin.Exp.Allergy 2001,31(9),1432-1440)。此外,众所周知响应于变应素,存在肥大细胞向鼻粘膜上皮内层的重新分配(Fokkens,W.J.等人,Clin.Exp.Allergy 1992,22(7),701-710;Slater,A.等人,J.Laryngol.Otol.1996,110,929-933)。这些结果表明,肥大细胞的趋化反应由组胺H4受体介导。
已经表明,嗜酸性细胞可以趋化到组胺(O′Reilly,M.等人,J.Recept.Signal Transduction 2002,22(1-4),431-448;Buckland,K.F.等人,Br.J.Pharmacol.2003,140(6),1117-1127;Ling等人,2004)。利用H4选择性配体,已经表明组胺-诱发的嗜酸性细胞趋化性由H4受体介导(Buckland等人,2003;Ling等人,2004)。在组胺处理之后,粘着分子CD11b/CD18(LFA-1)和CD54(ICAM-1)在嗜酸性细胞上的细胞表面表达得到促进(Ling等人,2004)。该增强被H4受体拮抗剂阻断,而不是被H1、H2或者H3受体拮抗剂阻断。
H4R还在树状细胞和T细胞中起作用。在人类单核细胞-起源的树状细胞中,H4R的刺激抑制IL-12p70形成和推进组胺-介导的趋化性(Gutzmer,R.等人,J.Immunol.2005,174(9),5224-5232)。H4受体在CD8+T细胞中的作用同样已经被报道。Gantner等人,(2002)表明,H4和H2受体都控制组胺-诱发的IL-16从人类CD8+T细胞中释放。IL-16发现于变应素-或者组胺-激发的哮喘患者的支气管肺泡流体中(Mashikian,V.M.等人,J.Allergy Clin.Immunol.1998,101(6,Part 1),786-792;Krug,N.等人,Am.J.Resp.Crit.Care Med.2000,162(1),105-111),并且被认为在CD4+细胞迁移中是非常重要的。该受体在这些细胞类型的活性表明了其在适应性免疫响应中的重要作用,比如在自身免疫疾病中的那些活性。
在体内,H4受体拮抗剂能够阻断酵母聚糖-诱发的腹膜炎或者胸膜炎模型中的neutrophillia(Takeshita,K.等人,J.Pharmacol.Exp.Ther.2003,307(3),1072-1078;Thurmond等人,2004)。此外,H4受体拮抗剂在结肠炎的广泛应用和充分表征的模型中具有活性(Varga,C.等人,Eur.J.Pharmacol.2005,522(1-3),130-138)。这些结果支持了H4受体拮抗剂具有体内抗炎能力的结论。
组胺的另一生理学作用是作为疥疮的介质和H1受体拮抗剂在临床中不能完全有效。最近,H4受体还涉及小鼠中组胺-诱发的搔抓(Bell,J.K.等人,Br.J.Pharmacol.2004,142(2),374-380)。组胺的上述作用可以被H4拮抗剂阻断。这些结果支持了H4受体在组胺-诱发的疥疮中被涉及和H4受体拮抗剂由此将在治疗瘙痒中具有积极作用的假设。
H4受体的调节作用控制炎性介质的释放和抑制白细胞的补充,由此提供预防和/或治疗H4-介导的疾病和状况的能力,包括变应性响应(比如炎症)的有害作用。根据本发明的化合物具有H4受体调节性能。根据本发明的化合物具有抑制白细胞补充的性能。根据本发明的化合物具有抗炎的性能。
炎症主题的教科书的实例包括:1)Gallin,J.I.;Snyderman,R.,Inflammation:Basic Principles and Clinical Correlates,第三版;LippincottWilliams & Wilkins:Philadelphia,1999;2)Stvrtinova,V.等人,Inflammation and Fever.Pathophysiology Principles of Diseases(Textbookfor Medical Students);Academic Press:New York,1995;3)Cecil等人;Textbook Of Medicine,第十八版;W.B.Saunders Co.,1988;和4)Stedman’s Medical Dictionary。
关于与炎症相关的炎症和状况的背景和综述材料可以发现于论文中,比如以下:Nathan,C.,Nature 2002,420(6917),846-852;Tracey,K.J.,Nature 2002,420(6917),853-859;Coussens,L.M.等人,Nature 2002,420(6917),860-867;Libby,P.,Nature 2002,420,868-874;Benoist,C.等人,Nature 2002,420(6917),875-878;Weiner,H.L.等人,Nature 2002,420(6917),879-884;Cohen,J.,Nature 2002,420(6917),885-891;Steinberg,D.,Nature Med.2002,8(11),1211-1217。
由此,根据本发明的小分子组胺H4受体调节剂控制炎症介质的释放和抑制白细胞补充,并且可以用于治疗多种病因学炎症,包括以下状况和疾病:炎性病症、变应性紊乱、皮肤病、自身免疫病、淋巴管病症、瘙痒和免疫缺陷病症。由组胺H4受体活性介导的疾病、病症和医疗状况包括本文提及的那些。
2-芳基苯并咪唑已经被公开为组胺H4受体调节剂,参见:U.S.PatAppl.Publ.2005/0070550A1。然而,仍然需要具有合意的药物性能的有效组胺H4受体调节剂。

本发明的详细说明
通过参考以下说明书,包括以下术语汇编和结论实施例,本发明可以得到更全面地理解。为了简短起见,在该说明书中引用的公开文献(包括专利)的公开内容在此引入作为参考。
如本文中所应用,术语“包括”、“包含”和“含有”在此以它们的开放、非限定意义使用。
术语“烷基”是指在链上具有1~12个碳原子的直链或者支链烷基。烷基的实例包括甲基(Me,还可以由符号“/”进行结构表示)、乙基(Et)、正丙基、异丙基、丁基、异丁基、仲丁基、叔丁基(tBu)、戊基、异戊基、叔戊基、己基、异己基,和根据本领域的普通技能和在此提供的教导将被认为等同于任何上述实例的基团。
术语“烯基”是指在链上具有2~12个碳原子的直链或者支链烯基。(烯基的双键由两个sp2杂化碳原子形成。)例证性的烯基包括丙-2-烯基、丁-2-烯基、丁-3-烯基、2-甲基丙-2-烯基、己-2-烯基,和根据本领域普通技能和本文提供的教导被认为相当于任何上述实例的基团。

“杂环烷基”是指饱和或者部分饱和并且每个环结构具有3~12个选自碳原子和至多三个选自氮、氧和硫的杂原子的环原子的单环或者稠合、桥接或者螺多环结构。所述环结构可以任选在碳或者硫环成员上含有至多两个氧代基团。为适当键接的部分的形式的例证性实体包括:
术语“杂芳基”是指每个杂环具有3~12个环原子的单环、稠合双环或者稠合多环芳香杂环(环结构具有选自碳原子和至多四个选自氮、氧和硫的杂原子的环原子)。杂芳基的例证性实例包括以下为适当键接的部分的形式的实体:
本领域熟练技术人员应当认可,以上列举或者说明的杂芳基、环烷基和杂环烷基种类并不是穷尽性的,还可以选择在这些定义术语范围的另外种类。
术语“卤素”表示氯、氟、溴或者碘。术语“卤代”表示氯代、氟代、溴代或者碘代。
术语“取代的”是指具体的基团或者部分上带有一个或者多个取代基。术语“未被取代的”是指具体的基团上不带有取代基。术语“任选取代的”是指具体的基团未被取代或者被一个或者多个取代基取代。当术语“取代的”用于描述结构系统时,取代是指在系统上任何化合价-允许的位置上存在。
为了提供更为简洁的说明,在本文中给出的一些数量表达并没有用术语“约”限定。应当理解,无论术语“约”是否明确使用,在本文中给出的每个数量都是指实际的给定值,并且它还指基于本领域普通技术可以合理推断的所述给定值的近似值,包括由于所述给定值的试验和/或测量条件而得到的等价值和近似值。任何时候当产率以百分比给出时,所述产率是指相对于根据具体化学计量条件可以获得相同实体的最大量给出产率的实体质量。以百分比给出的浓度,除非另外表明,是指质量比。
任何在此给出的式意图表示具有所述结构式表明的结构的化合物以及某些变体或者形式。特别是,在此给出的任何式的化合物可以具有不对称中心,和由此以不同的光学异构形式存在。通式化合物的所有旋光异构体和立体异构体及其混合物都认为在该式的范围之内。由此,在此给出的任何式意图表示外消旋物、一种或者多种光学异构形式、一种或者多种非对映形式、一种或者多种阻转异构体形式及其混合物。
此外,某些结构可以以几何异构体(即,顺反异构体)、互变异构体或者阻转异构体存在。另外,任何在此给出的式意图表示所述化合物的水合物、溶剂化物和多晶型物及其混合物。
在本文中涉及的化学实体表示涉及以下任何一种:(a)所述化学实体的实际描述的形式,和(b)当命名时考虑化合物时,介质中的所述化学实体的任何形式。例如,在本文中涉及的比如R-COOH的化合物,包括涉及任何一种以下形式,例如R-COOH(s)、R-COOH(sol)和R-COO- (sol)。在该实施例中,R-COOH(s)是指固体化合物,其例如可以为片剂或者一些其它固体药物组合物或者制剂的形式;R-COOH(sol)是指在溶剂中未离解的化合物形式;和R-COO- (sol)是指在溶剂中离解的化合物形式,比如化合物在含水环境中的离解形式,无论所述离解形式由R-COOH、其盐或者通过在考虑的介质中离解产生R-COO-的任何其它实体衍生得到。在另一实例中,比如“将实体暴露于式R-COOH的化合物”的表达是指将所述实体暴露于在进行所述暴露的介质中存在的化合物R-COOH的形式。关于这一点,如果所述实体例如在含水环境中,应当理解,化合物R-COOH在相同介质中,并且由此使该实体暴露于比如R-COOH(aq)和/或R-COO- (aq)的物质,其中下标“(aq)”表示与其在化学和生物化学中常规含义相应的“含水”。在这些命名实施例中选择了羧酸官能团;然而,该选择并非意图进行限定,而仅仅是一种例证说明。应当理解,可以对其它官能团提供类似的实施例,包括但不限于羟基、碱性氮成员(比如在胺中的那些碱性氮成员)和在含有化合物的介质中根据已知的方式相互作用或者转化的任何其它基团。所述相互作用和转化包括但不限于离解、结合、互变异构、溶剂解(包括水解)、溶剂化(包括水合)、质子化和去质子化。在另一实例中,在本文中包括两性离子化合物,其是指已知形成两性离子的化合物,即使没有以它的两性离子形式进行明确命名。比如一种或多种两性离子和它们的同义词两性离子化合物的术语是熟知的标准IUPAC-认可的名称和属于规定的科学术语标准组的一部分。就此而言,名称两性离子由Chemical Entities ofBiological Inerest(ChEBI)dictionary of molecular entities指定为名称标识CHEBI:27369。(参见,例如它的在线版本,http://www.ebi.ac.uk/chebi/init.do)。如通常所熟知,两性离子或者两性离子化合物是具有相反符号的形式单位电荷的中性化合物。有时,这些化合物由术语“内盐”表示。其它资料来源将这些化合物称为“两极离子”,不过后面的术语被另一些其它资料来源认为是误称。作为具体的实例,氨基乙酸(氨基甘氨酸)的化学式为H2NCH2COOH,和它在一些介质(在该情形中为中性介质)中以两性离子+H3NCH2COO-的形式存在。两性离子、两性离子化合物、内盐和两极离子以这些术语的已知和充分确定含义包括在本发明范围内,在任何情形中本领域普通技术人员都应当如此理解。因为不必命名本领域普通技术人员可以确认的每一个实施方案,因此在此没有明确给出与本发明化合物相关的两性离子化合物的结构。然而,它们属于本发明的实施方案。就此方面在本文中未进一步提供实施例,这是因为这些在给定介质中的相互作用和转化对于任何本领域普通技术人员是已知的。
在本文中给出的任何化学式还意图表示所述化合物的未标记形式以及同位素标记形式。同位素标记的化合物具有本文中给出的化学式所表明的结构,但是一个或者多个原子被具有选定原子量或者质量数的原子替换。可以包含在本发明化合物中的同位素的实例包括氢、碳、氮、氧、磷、氟、氯和碘的同位素,比如分别为2H、3H、11C、13C、14C、15N、18O、17O、31P、32P、35S、18F、36Cl、125I。所述同位素标记的化合物可以用于新陈代谢研究(优选14C)、反应动力学研究(例如2H或者3H)、包括药物或者基质组织分布测定的检测或者成像工艺[比如正电子发射层析成象(PET)或者单-光子发射计算层析成象(SPECT)]或者患者的放射性治疗中。特别是,18F或者11C标记的化合物可以特别优选用于PET或者SPECT研究。此外,用较重同位素(比如氘,即2H)取代可能会提供某些源于更强的新陈代谢稳定性(例如,延长的体内半衰期或者降低的剂量需要)的治疗学优点。本发明的同位素标记化合物及其前药通常可以通过进行以下方案或者实施例中公开的方法和以下所述的制备,用可以轻易获得的同位素标记试剂替换非同位素标记的试剂得到制备。
当涉及在此给出的任何式时,从具体变量的可能物质列表中进行的具体部分的选择并不意图将在其它地方出现的该变量的物质限定为相同选择。换言之,当变量出现不止一次时,除非另有说明,从具体列举中进行的物质选择独立于式中其它地方的相同变量的物质选择。
通过关于取代基命名的第一实例,如果取代基S1 实例是S1和S2中的一种,和取代基S2 实例是S3和S4中的一种,那么这些赋值是指根据以下选择给出的本发明实施方案,S1 实例为S1和S2 实例为S3;S1 实例为S1和S2 实例为S4;S1 实例为S2和S2 实例为S3;S1 实例为S2和S2 实例为S4;以及各种等同的所述选择。较短的术语“S1 实例是S1和S2中一种,和S2 实例是S3和S4中一种”是为了简要起见而在此相应使用的术语,并不是籍此进行限制。在通用术语中所述的以上关于取代基术语的第一实例应当理解说明各种在本文中所述的取代基赋值。适当时,在本文中针对取代基给出的上述惯例延伸至比如R1-11、X1、X2和n的成员以及在本文中使用的任何其它一般取代基符号。
此外,当将多于一种赋值给予任何成员或者取代基时,本发明的实施方案包括可以由所列举的独立采用的赋值及其等价赋值构成的各种组合。通过关于取代基命名的第二实例,如果在本文中描述取代基S实例为S1、S2和S3中的一种,该列举是指以下本发明实施方案,S实例为S1;S实例为S2;S实例为S3;S实例为S1和S2中的一种;S实例为S1和S3中的一种;S实例为S2和S3中的一种;S实例为S1、S2和S3中的一种;和S实例为各种所述选择的任何等价赋值。较短的术语“S实例是S1、S2和S3中的一种”是为了简要起见而在此相应使用的术语,并不是籍此进行限制。在通用术语中所述的以上关于取代基术语的第二实例应当理解为说明各种在本文中所述的取代基赋值。适当时,在本文中给出的上述惯例延伸至比如R1-11、X1、X2和n的成员以及在本文中使用的任何其它一般取代基符号。
命名“Ci-j”,其中j>i,当在此将其用于一类取代基时,是指从i至j(包括i和j)每一种数目的碳原子的本发明实施方案独立地得到了实现。例如,术语C1-3独立地是指具有一个碳原子成员(C1)的实施方案、具有两个碳原子成员(C2)的实施方案和具有三个碳原子成员(C3)的实施方案。
术语Cn-m烷基指在链上具有总数N个碳原子成员的直链或者支链脂肪链,其满足n≤N≤m,同时m>n。
当允许存在多于一种所述连接可能性时,任何在本文中提及的二取代基是指包括各种连接可能性。例如,参考二取代基-A-B-,其中A≠B,在本文中是指A连接在第一取代成员和B连接在第二取代成员上的所述二取代基,和它还指A连接在第二取代成员和B连接在第一取代成员上的所述二取代基。
根据上述对赋值和命名进行的解释性说明,应当理解,在本文中对设定的明确涉及,其中在化学性质上有意义和除非另有说明,暗示了独立地涉及所述设定的实施方案,和涉及所明确涉及的设定的设定子集的每种可能实施方案。
在式(I)或者式(II)的一些实施方案中,R1-4各自独立地为H、甲基、叔丁基、甲氧基、氟、氯、甲氧羰基或者苯甲酰基。
在一些实施方案中,n为1。

本发明的式(I)或者式(II)化合物和它们的药学上可接受的盐、药学上可接受的前药和药学上的活性代谢物(总称为“试剂”)可以在本发明方法中用作组胺H4受体调节剂。所述试剂可以在本发明方法中用于治疗或者预防通过组胺H4受体调节介导的医疗状况、疾病或者病症,比如在此所述的那些。因此,根据本发明的试剂可以用作消炎药。症状或者疾病状态意图包括在“医疗状况、病症或者疾病”的范围内。
据此,本发明涉及使用在此所述的药物试剂治疗诊断有或者患有通过组胺H4受体活性介导的疾病、病症或者状况,比如炎症,的对象的方法。
在优选的实施方案中,给药本发明试剂治疗炎症。炎症可以与多种疾病、病症或者状况相关,比如炎性病症、变应性紊乱、皮肤学病症、自身免疫病、淋巴管病症和免疫缺陷病症,包括以下给出的更具体状况和疾病。关于炎症、炎性疾病或者炎症-介导的疾病或者状况的发作和进展包括但不限于急性炎症、变应性炎症和慢性炎症。
可以用根据本发明的组胺H4受体-调节剂治疗的炎症的例证性类型包括由于任何一种以下多种状况导致的炎症,比如过敏反应、哮喘、干眼、慢性阻塞性肺病(COPD)、动脉粥样硬化症、类风湿性关节炎、多发性脑硬化、肠炎疾病(包括结肠炎、克罗恩病和溃疡性结肠炎)、牛皮癣、瘙痒、疥疮皮肤、特异性皮炎、风疹(荨麻疹)、眼睛炎症、结膜炎、鼻息肉、过敏性鼻炎、鼻发痒、硬皮症、自身免疫甲状腺病、免疫-介导(亦称1型)糖尿病和狼疮,其特征在于,在疾病的某些阶段具有过度或者延长的炎症。其它引起炎症的自身免疫疾病包括重症肌无力、自身免疫神经病,比如格-巴二氏病、自身免疫葡萄膜炎、自身免疫性溶血性贫血、恶性贫血、自身免疫血小板减少症、颞动脉炎、抗磷脂综合征、血管炎比如韦格纳氏肉芽肿病、贝切特氏病、疱疹样皮炎、寻常天疱疮、白癜风、原发性胆汁性肝硬变、自身免疫肝炎、自身免疫卵巢炎和睾丸炎、肾上腺自身免疫病、多肌炎、皮肤肌炎、脊柱关节病(比如强直性脊柱炎)和斯耶格伦氏综合征。

一旦患者的疾病、病症或者状况已经发生改善,可以调整剂量以预防或者维持治疗。例如,可以根据症状将给药的剂量或者频率或者二者都降低至保持期望的治疗学或者预防学作用的水平。当然,如果症状已经被减轻到适当的水平,治疗可以停止。然而,当任何症状复发时,患者可能需要长期间歇治疗。
此外,在以上状况的治疗中,本发明试剂可以协同另外的活性化合物使用。另外的化合物可以与式(I)或者式(II)的试剂分离共同给药,或者将所述试剂作为另外的活性成分一起包含在根据本发明的药物组合物中。在例证性的实施方案中,另外的活性化合物是已知或者发现在组胺H4受体活性介导的状况、病症或者疾病的治疗中有效的那些,比如其它组胺H4受体调节剂或者对与具体状况、病症或者疾病相关的另一靶点具有活性的化合物。所述组合可以用于增强效力(例如,通过将化合物包含在组合内增强根据本发明的试剂的效能或者有效性)、降低一种或者多种副作用或者降低根据本发明的试剂的所需剂量。
当涉及调节目标受体时,“有效量”表示足以影响所述受体活性的量。测量目标受体的活性可以通过常规分析方法进行。目标受体调节作用可以用于多种设置中,包括测定。

在以下所示的方案中,本领域熟练技术人员应当认可,R11可以被替换为适宜的氮保护基,比如叔丁氧羰基(Boc),和在合成的后续步骤中替换该保护基。
方案A
关于方案A,胺A2可以市场购买到或者由酸A1或者醇A3制备得到。在比如二环己基-碳二亚胺、EDC/HOBt或者羰基二咪唑的活化剂存在下,在比如DMF或者THF的溶剂中偶联酸A1与胺R6NH2,提供相应的酰胺(未显示)。另外地,将酸A1活化成它们的相应酰基氯和在适宜的碱(比如三乙胺或者二异丙基乙胺)存在下,在比如DCM或者THF的溶剂中使其与胺R6NH2反应。在比如THF的溶剂中,通过适宜的还原剂(比如LiAlH4),将所得酰胺还原成胺A2。醇A3利用一般方法进行活化,从而形成,例如烷基卤化物或者烷基甲苯磺酸酯。在适宜的碱(比如NaH、NaOH、三乙胺或者二异丙基乙胺)存在下,在比如DCM或者THF的溶剂中,用R6NH2进行置换,提供胺A2。另外地,胺A2由醇A3通过与苯邻二甲酰亚胺或者适宜的氨基替代品在Mitsunobu条件下反应得到制备。当使用苯邻二甲酰亚胺时,通过用肼处理,产生游离胺。

方案C
关于方案C,酸A1或者醇A3可以利用方案A中所述的方法与2-氨基吡啶C1偶联,从而形成酰胺和胺C2。化合物C2如方案B所述进行处理,从而提供式(I)化合物。
式(II)化合物利用类似于对式(I)化合物所述的方法进行制备,但是其中吡啶B1由N-氧代类似物、2-氯-1-氧基-异烟酸腈(isonicotinonitrile)替换。
另外的合成方法描述在U.S.Pat.Appl.Publ.2005/0070550A1中,其在此引入作为参考。
根据如上所述的方案制备的化合物可以获得为单个对映异构体、非对映异构体或者区域异构体,或者获得为外消旋混合物或者对映异构体、非对映异构体或者区域异构体的混合物。当获得区域异构体或者非对映体混合物时,可以利用常规方法(比如色谱法或者结晶)对异构体进行分离。当获得外消旋物(1:1)和对映异构体的非外消旋(非1:1)混合物时,可以利用本领域熟练技术人员已知的常规分离方法对单个异构体进行分离。特别有效的分离方法可以包括手性色谱法、重结晶、非对映盐形成或者衍生为非对映体加合物随后进行分离。
