摘 要:通过对抗肿瘤药物马来酸阿法替尼合成工艺的研究,开发适合工业化生产的合成工艺,并放大至单批次近2kg级规模。以6-硝基-4-[(3-氯-4-氟苯基)氨基]-7-氯喹唑啉(3)为原料,与S-羟基四氢呋喃(4)经反应后利用锌粉-醋酸体系还原,得到的固体在CDI存在下与2-(二乙氧基磷酰基)乙酸(7)反应后与N,N-二甲氨基乙醛(9)经Horner-Wadsworth-Emmons反应得到的阿法替尼碱(2)与马来酸在THF中常温搅拌成盐而合成马来酸阿法替尼(1),纯度>99%,总收率61.3%(以3计)。By studying the synthesis process of afatinib dimaleate, a antitumor drug, the synthetic process suitable for industrial production was developed and magnified to about 2 kg grade per batch. 6-nitro-4-[(3-chloro-4-fluorophenyl) amino]-7-chloroquinazoline(3) as raw material, was reacted with S-hydroxytetrahydrofuran(4), then reduced using zinc powder-acetic acid system. The acquired solid reacted with 2-(diethoxyphosphoryl) acetic acid(7) in the presence of CDI, and then reacted with N, N-dimethylaminoethanal(9) via Horner-Wadsworth-Emmons reaction. The obtained afatinib(2) stirred at room temperature with maleic acid in THF solution to synthesize afatinib dimaleate(1). The purity of the product>99 % and total recovery is 61.3 %(based on 3).
