Prasugrel hydrochloride (1), an important platelet inhibitor is used for the reduction of thrombotic cardiovascular events. During laboratory optimization and later its bulk synthesis the formation of various impurities was observed. The impurities formed were monitored and their structures were tentatively assigned on the basis of their fragmentation patterns in LC-MS. Most of the impurities were synthesized and their assigned constitutions confirmed by co-injection in HPLC. We describe herein the formation, synthesis and characterization of these impurities. Present study will be of immense help to others to obtain chemically pure prasugrel hydrochloride.
盐酸普拉格雷 (1) 是一种重要的血小板
抑制剂,用于减少血栓性心血管事件。在实验室优化和后来的批量合成过程中,观察到了各种杂质的形成。对形成的杂质进行了监测,并根据它们在 LC-MS 中的碎片模式初步确定了它们的结构。大多数杂质都已合成,并通过在 HPLC 中共同进样确认了其指定结构。我们在此介绍这些杂质的形成、合成和表征。本研究将对其他人获得
化学纯
盐酸普拉格雷有很大帮助。
