摘要:以 3-(2-氯嘧啶-4-基)-1-甲基吲哚为原料,经取代、缩合、还原和酰胺化以及成盐 4 步反应,得到目标化
合物奥斯替尼甲磺酸盐,总收率为 41.9%。通过单因素实验对每步反应的关键参数进行了优化,得到一条快速、
高效的合成路线。在还原和酰胺化反应过程中采用一锅法不仅简化了操作步骤,同时解决了中间产物不稳定难于
分离纯化的问题,3-(2-{[4-(N,N,N-三甲基乙二胺基)-2-甲氧基-5-硝基]苯胺基}嘧啶-4-基)-1-甲基吲哚(Ⅴ)合成
Osimertinib 的收率也由文献的 33%提升到 61%。此外,在该过程中以廉价的丙烯酸代替丙烯酰氯,不仅降低了
成本,并且反应条件更加温和、易于操作。

Abstract: Osimertinib mesylate in a total yield of 41.9% was obtained via four steps of substitution,
condensation, reduction and amidation, and salt formation with 3-(2-chloropyrimidin-4-yl)-1-methylindole
as raw material. The key parameters of each step were optimized by single factor experiment and a fast
and efficient synthetic route was obtained. The “one-pot method” used in the process of reduction and
amidation not only simplifies the operation steps, but also solves the problem that the intermediate
product is unstable and difficult to separate and purify. And the yield of osimertinib from 3-(2-{[4-(N,N,N-
trimethylethylenediamineyl)-2-methoxy-5-nitro]phenylamino}pyrimidin-4-yl)-1-methylindole(Ⅴ) reached
61%, higher than that reported in the literature (33%). Besides, in this process, acryloyl chloride was
replaced by cheap acrylic acid, which not only reduced costs, but also made the reaction conditions milder
and easier to operate.
