An efficient, practical, and commercially viable manufacturing process was developed with ≥99.7% purity and 31% overall yield (including four chemical reactions and one recrystallization) for an active pharmaceutical ingredient, called Metopimazine (1), an antiemetic drug used to prevent emesis during chemotherapy. The development of two in situ, one-pot methods in the present synthetic route helped
开发了一种有效,实用且商业上可行的制造工艺,其纯度≥99.7%,总收率31%(包括四个化学反应和一个重结晶)(称为美托咪嗪(1)),这是一种用于防止呕吐的止吐药,是一种活性药物成分。在化疗期间。与先前的报道(<15%)相比,当前合成路线中两种原位单罐方法的开发有助于提高总产量1(31%)。首次提供了API(1),中间体和可能存在的杂质的表征数据。关键流程问题和挑战得到有效解决并成功实现。
