An improved process has been developed for the synthesis of 5-bromo-3-(1-methylpiperidin-4-yl)-1H-indole, a key intermediate of naratriptan hydrochloride, which is used as a drug for migraine. A novel one-pot synthetic procedure using triethyl silane was developed for scale-up.
已经开发出一种改进的方法,用于合成5-溴-3-(1-甲基哌啶-4-基)-1 H-吲哚,其是盐酸那拉曲普坦的关键中间体,被用作偏头痛药物。为扩大规模,开发了一种使用三乙基硅烷的新型一锅法合成程序。
