Sertindole (1), an atypical anti-psychotic drug is used for the treatment of schizophrenia. During the laboratory optimization and later during 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. Our study will be of immense help to others to obtain chemically pure sertindole.
Sertindole(1),一种非典型抗精神病药物,用于治疗精神分裂症。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。这些杂质的形成得到了监测,并根据它们在LC-MS中的碎片图谱初步确定了它们的结构。大多数杂质已经合成,并通过HPLC共注射确认了它们的构成。我们在此描述了这些杂质的形成、合成和表征。我们的研究将对他人获得化学纯净的Sertindole有巨大的帮助。
