The present invention provides efficient, economical, and improved methods for synthesizing ibrutinib and intermediates thereof. The invention involves a unique biphasic acylation reaction system which advantageously allows for easy separation of ibrutinib from the reaction mixture without additional extraction and wash steps. The isolated ibrutinib formed using the methods described herein can be useful in the preparation of an amorphous form of ibrutinib. In some embodiments, the isolated ibrutinib produced by the processes described herein is a homogenous solution of ibrutinib and DMSO which may be directly used in the formation of the amorphous polymorph. In some embodiments, the isolated ibrutinib is solid ibrutinib. The solid ibrutinib may also be used in the formation of amorphous ibrutinib.
本发明提供了一种有效、经济、改进的方法,用于合成依布替尼及其中间体。该发明涉及一种独特的两相酰化反应体系,其优点在于可以轻松地从反应混合物中分离出依布替尼,无需额外的萃取和洗涤步骤。使用本文所述方法制备的分离出的依布替尼可以用于制备依布替尼的非晶态形式。在某些实施例中,使用本文所述的方法产生的分离出的依布替尼是依布替尼和二甲基亚砜的均质溶液,可直接用于形成非晶态多晶体。在某些实施例中,分离出的依布替尼是固态依布替尼。固态依布替尼也可用于形成非晶态依布替尼。
