Description

1-[2-(2,4-二甲基苯基硫烷基)-苯基]哌嗪的制备方法
技术领域
本发明属于药物合成技术领域,具体涉及一种低成本、绿色环保的制备1-[2-(2,4-二甲基苯基硫烷基)-苯基]哌嗪的合成方法。
背景技术
1-[2-(2,4-二甲基苯基硫烷基)-苯基]哌嗪为二芳基硫醚胺类物质,其氢溴酸盐(Lu AA21004,Vortioxetine Hydrobromide)是一类新的化学类抗抑郁药物;主要用于治疗抑郁症和焦虑症。该产品为Lundbeck和Takeda共同研发,2012.09,通过集中审评程序在欧洲提交用于抑郁症的MAA申请;2012.10,在美国提交用于治疗成人重度抑郁症(MDD)的NDA申请。在专利WO03029232中,该化合物被公开,且受到专利保护;在WO2007144005的分案专利CN102617513A中,具体保护了该化合物的制备方法。其保护的重点如下所示:
上述保护的整体思路基本可归纳为下述两种:
该专利从溶剂、碱以及所使用的钯源等诸多因素对上述路线进行了保护;关键是该专利运用了多种钯的重金属催化剂,而在药物合成中,其重金属尤其是钯是需要严格限制的;更为重要的是,采用专利的合成方法,会导致反应过程中其它偶联杂质产生,给后续纯化带来困难。
