摘要:
为了评估和开发阿伐曲泊帕的合成工艺,设计了汇聚型合成策略对其进行合成研究。分别以6-羟基烟酸为原料合成5,6-二氯烟酸;以异烟酸为原料合成4-哌啶甲酸乙酯;以无水哌嗪为原料合成1-环己基哌嗪,而后利用这些模块构建了关键中间体5-氯-6-[4-(乙氧基羰基)哌啶-1-基]吡啶-3-羧酸和4-(4-氯噻吩-2-基)-5-(4-环己基哌嗪-1-基)噻唑-2-胺,最后再进行缩合得到阿伐曲泊帕。整个工艺路线条件温和,可操作强,整体收率达到48.8%,此外,所得到的化合物及中间体都进行质谱、核磁等表征,其波谱数据与化合物结构吻合。

Abstract:
A convergent synthetic strategy was developed for the synthesis of avatrombopag. Firstly, 5,6-dichloronicotinic acid, ethyl 4-piperidinecarboxylate and 1-cyclohexylpiperazine were synthesized using 6-hydroxynicotinic acid, isonicotinic acid and piperazine as reactants, respectively, which then acted as the building blocks for construction of the key intermediates 5-chloro-6-[4-(ethoxycarbonyl)piperidine-1-yl] pyridine-3-carboxylic acid and 4-(4-chlorothiophen-2-yl)-5-(4-cyclohexylpiperazin-1-yl)thiazol-2-amine. Finally, avatrombopag was obtained by the condersation of the two intermediates. The reaction conditions are mild and practical, and the overall yield is up to 48.8%. Furthermore, the obtained compounds and intermediates were characterized by mass spectrometry and 1H nuclear magnetic resonance spectroscopy, and all spectral data are consistent with the structures of the compounds.
