    • Disclosed herein are a process or method for the preparation of prasugrel and several novel crystalline forms of prasugrel hydrochloride. The process comprises preparation of prasugrel by acetylation in solvents which have low boiling point and/or low toxicity, and the process not only avoids using solvents which have high boiling point and/or high toxicity such as toluene, acetonitrile and so on, but also resolves the problem about thermal instability of prasugrel, and the loss of prasugrel is reduced, as well as the yield is raised. The yield of prasugrel is higher than 85% and the purity is higher than 99.5%. The process can prepare prasugrel and its pharmaceutically acceptable salts. The novel crystalline forms of prasugrel hydrochloride are crystalline form H1, H2 and H3, and their performance in oral absorbability, activating metabolism and inhibiting platelet aggregation is excellent. They have a low toxicity and good thermal stability, and are applicable to the preparation of a drug for preventing or treating diseases caused by thrombosis or embolism.
    • 本文公开了制备普拉格雷和几种新型的普拉格雷盐酸盐结晶形式的方法或方法。 该方法包括通过在低沸点和/或低毒性的溶剂中乙酰化制备普拉格雷,并且该方法不仅避免使用具有高沸点和/或高毒性的溶剂如甲苯,乙腈等,而且还可以 解决普拉格雷热不稳定问题,降低普拉格雷的损失,提高产量。 普拉格雷的产量高于85%,纯度高于99.5%。 该方法可以制备普拉格雷及其药学上可接受的盐。 普拉格雷盐酸盐的新型结晶形式是H1,H2和H3结晶,口服吸收性能,活化代谢和抑制血小板聚集性能优异。 它们具有低毒性和良好的热稳定性,适用于预防或治疗由血栓形成或栓塞引起的疾病的药物的制备。
