Description

一种吡咯并氨基哒嗪酮化合物的制备方法及其中间体
本申请要求申请日为2018年8月22日的中国专利申请CN201810958690.X的优先权。本申请引用上述中国专利申请的全文。
技术领域
本公开涉及一种吡咯并氨基哒嗪酮化合物的制备方法及其中间体。
背景技术
免疫细胞通常可以分为T细胞与B细胞两类，其中B细胞的主要职能是分泌各种抗体帮助人体抵御各种外来的侵入。Bruton酪氨酸蛋白激酶(BTK)是酪氨酸蛋白激酶亚家族的成员之一，属于Tec家族激酶，主要在B细胞中表达，分布于淋巴系统、造血及血液系统。B细胞受体(BCR)对于包括慢性淋巴细胞性白血病(CLL)和非霍奇金淋巴瘤的(NHL)亚型，套细胞淋巴瘤(MCL)，和弥漫性大B细胞淋巴瘤(DLBCL)在内的多种淋巴瘤的增殖及生存具有至关重要的调控作用，此外，B细胞在类风湿关节炎，系统性红斑狼疮，多发性硬化症，以及其他免疫疾病的发病机制中的作用已被临床证实。Bruton酪氨酸蛋白激酶(BTK)是BCR信号通路中的一个关键的蛋白激酶。能够调节正常B细胞的成熟、分化，也与多种B细胞淋巴组织失调疾病密切相关。因此，靶向小分子抑制剂BTK可对B细胞恶性肿瘤和自身免疫疾病的治疗提供效益。
WO2016007185A1涉及一种式(Ia)化合物，即(R)-4-氨基-1-(1-(丁-2-炔酰基)吡咯烷-3-基)-3-(4-(2,6-二氟苯氧基)苯基)-1,6-二氢-7H-吡咯并[2,3-d]哒嗪-7-酮，该化合物为新型BTK激酶抑制剂，在激酶选择性，临床疗效或适应症，及安全性等方面均有所改善，其结构如下所示：
Figure PCTCN2019101790-appb-000001
WO2016007185A1的实施例1、中间体2和实施例93公开了该化合物的制备方法，总计十步反应，具体反应如下所示：
Figure PCTCN2019101790-appb-000002
该方法在制备93c化合物的产率仅为22.8％、产物93的产率仅为51％，整个方法中存在多个反应步骤的产率偏低、纯化困难，使得该路线的总收率较低且放大可行性较差，并且方法中用到钯催化剂，成本较高，因此，有必要改进现有的制备方法。
