Description
技术领域
本发明属于有机合成技术领域,具体涉及一种维奈托克关键中间体及原料药的合成方法。
背景技术
维奈托克(Venetoclax)是全球首个B细胞淋巴瘤因子-2(Bcl-2)选择性抑制剂药物,曾获得美国FDA三个突破性药物资格(突破性药物认定、优先审查资格和加速审批资格)和孤儿药地位,于2016获美国FDA批准上市,鉴于其优良的临床疗效,适应症逐步扩大,被批准用于治疗慢性淋巴细胞白血病、非霍奇金淋巴瘤、小淋巴细胞淋巴瘤、弥漫性大B-细胞淋巴瘤和多发性骨髓瘤等疾病。据Evaluate Pharma统计,2020年维奈托克(Venetoclax)已在全球50多个国家/地区上市销售,销售额达14亿美元。
维奈托克的中文化学名为:4-(4-{[2-(4-氯苯基)-4,4-二甲基-1-环己烯-1-基]甲基}呱嗪-1-基)-N-({3-硝基-4-[(四氢-2H-吡喃-4-基甲基)氨基]苯基}磺酰基)-2-(lH-吡咯并[2,3-b]吡啶-5-基氧基)苯甲酰胺。原料药化合物具有分子量大,分子结构复杂,合成难度高等特点,维奈托克的化学结构式如下:
维奈托克原料药常见的合成路线已见如下专利报道:PCT WO2016/024230Al、WO2017/156398Al、WO2018/029711A2、WO2018/225043Al、WO2019/135253Al,欧洲专利EP3412666Al,美国专利US9006438 B2,国内专利CN 104370905 A、CN 104876927 A、CN108997333A等。以上现有维奈托克的合成路线大都存在操作复杂、反应时间长、原料剧毒、工艺复杂等缺点。如都需要经历以5-溴-7-氮杂吲哚为原料,1位NH经三异丙基硅基于-78℃与正丁基锂和硼酸三甲酯反应,再在碱、过氧化氢条件下反应得到1-(三异丙基硅基)-5-羟基-7-氮杂吲哚,然后与2,4-二氟苯甲酸甲酯偶联得到2-[(1H-吡咯并[2,3-b]吡啶-5-基)氧基]-4-氟苯甲酸甲酯的过程。其中关键中间体1-(三异丙基硅基)-5-羟基-7-氮杂吲哚的制备,需要保护、取代、水解等过程,以及用到危险试剂正丁基锂步骤,制备成本较高。另外原料2,4-二氟苯甲酸甲酯分子结构中含有2个氟原子,反应选择性差,导致反应产率低,且纯化难度较大,这是造成合路线成本高的另一个原因。而且在反应过程中脱除TIPS保护基,导致底物中-OH与自身另外一分子N反应,导致产率很低。国内葛敏、许云雷等人公开了一种Bc1-2抑制剂ABT-199(Venetoclax)的合成方法,该方法以2-氟-4-硝基苯甲酸甲酯和5-羟基-7-氮杂吲哚为原料经取代、还原、环合、取代、水解、缩合等方法合成维奈托克,该方法避免了国外专利中多取代产率低,不好纯化的问题,增加了反应收率。但工艺过程中钯碳等昂贵催化剂,在中间体纯化中需用到柱层析等较为昂贵和繁琐的工艺步骤。
