摘要:
Methods of preparing a fenfluramine active pharmaceutical ingredient are provided. Aspects of the method include (a) hydrolyzing a 2-(3-(trifluoromethyl)phenyl)acetonitrile composition to produce a 2-(3-(trifluoromethyl)phenyl)acetic acid composition; (b) reacting the 2- (3-(trifluoromethyl)phenyl)acetic acid composition with acetic anhydride and a catalyst to produce a 1-(3-(trifluoromethyl)phenyl)propan-2-one composition; and (c) reductively aminating the 1-(3-(trifluoromethyl)phenyl)propan-2-one composition with ethylamine using a borohydride reducing agent to produce a fenfluramine composition. Also provided are compositions and pharmaceutical ingredients prepared according to the subject methods including a pharmaceutically acceptable salt of fenfluramine and having less than 0.2% by weight in total of trifluoromethyl regioisomers.
摘要(中):
提供了制备芬氟拉明活性药物成分的方法。 该方法的方面包括(a)水解2-(3-(三氟甲基)苯基)乙腈组合物以产生2-(3-(三氟甲基)苯基)乙酸组合物; (b)使2-(3-(三氟甲基)苯基)乙酸组合物与乙酸酐和催化剂反应以制备1-(3-(三氟甲基)苯基)丙-2-酮组合物; 和(c)用硼氢化物还原剂将乙胺还原胺化1-(3-(三氟甲基)苯基)丙-2-酮组合物以产生芬氟拉明组合物。 还提供了根据主题方法制备的组合物和药物成分,其包括氟苯丙胺的药学上可接受的盐并且具有小于0.2重量%的总计三氟甲基区域异构体。 p>
