Abstract

Description
本申请属于药物合成领域,具体地,涉及JAK抑制剂乌帕替尼中间体及其制备方法,此外还涉及JAK抑制剂乌帕替尼的制备方法。
类风湿性关节炎(RA),银屑病关节炎(PsA)具体发病原因不明,从医疗实践推测其与患者免疫功能存在部分缺陷有着重要的关系。类风湿性关节炎病程长,并因其多有免疫功能障碍,患者常因心血管、感染及肾功能受损等合并症而死亡。
目前JAK抑制剂是有效治疗此类免疫系统疾病的手段之一。其中,乌帕替尼(Upadacitinib)作为艾伯维公司治疗类风湿性关节炎、银屑病关节炎的实验性新药,是一种新型靶点JAK1抑制剂。JAK1是一种激酶,其在包括类风湿性关节炎(RA)、克罗恩病(CD)、溃疡性结肠炎(UC)、银屑病关节炎(PsA)等多种炎症性疾病的病理生理过程中发挥关键作用。目前,艾伯维公司也在评估乌帕替尼治疗其他免疫疾病的潜力,包括PsA、强直性脊柱炎和AS及特应性皮炎。目前乌帕替尼相关新药申请(NDA)已在美国食品药品监督管理局(FDA)递交。
目前为止,国内外关于乌帕替尼的相关专利报道也较少,主要报道的专利合成路线为原研艾伯维公司的合成路线(WO2017066775A1):
在WO2017066775中,还公开了上述合成路线中化合物A8的合成方法,如下所示:
此外,在比WO2017066775A1更早的文献报道中(WO2013043826A1),艾伯维 公司还报道了通过重氮甲烷亚甲基溴化的路线合成关键中间体A8,其合成路线如下:
上述两种合成中间体A8的路线均存在不足。其中专利WO2013043826A1报道的合成路线中使用了重氮化合物作为反应物料,存在较大的安全隐患,不利于进行工业化放大生产。而专利WO2017066775A1报道的合成路线采用中间体A9,而化合物A9为含硫化合物,其自身以及相应的原料的副产物都有明显的气味,不利于生产环境的保持并增加了硫化物作为副产品的废物排放,环境并不十分友好。因此,设计一条更加安全有效,能够保证环境友好且操作简便的合成路线是十分必要的。
另外,关于WO2017066775A1公开的合成路线采用的化合物A1,WO2006058120A1和CN106432246A中公开了如下所示的合成方法:
WO2006058120A1和CN106432246A公开的A1的合成方法,皆使用三甲基硅基乙炔作为合成砌块完成反应。然而三甲基硅基乙炔的相对成本较高。
此外,在WO2017066775A1公开的路线中,在由化合物A6制备化合物A7即乌帕替尼的步骤中,会不可避免地产生二取代杂质A15,影响了乌帕替尼产品的品质。
综上,现有技术的乌帕替尼的合成方法存在成本较高、环境不十分友好以及产品品质有待提高等不足,系统的解决这些问题,发展一条成本低廉,环境友好,品质可控的合成JAK1抑制剂乌帕替尼的合成方法有着现实的社会意义和经济价值。
