This work describes the process development and manufacture of an ampakine-type active pharmaceutical ingredient in clinical trials. A regioselective CDI-mediated amidation process was optimized for the subsequent couplings of two distinctive amines with a terephthalic acid substrate. Choice of the synthetic route, key scale-up issues, safety calorimetry, and optimization of all steps for multikilogram
这项工作描述了在临床试验中安帕金型活性药物成分的工艺开发和生产。优化了区域选择性CDI介导的酰胺化工艺,以使两种独特的胺与对苯二甲酸底物进行后续偶联。讨论了合成路线的选择,关键的放大问题,安全量热法以及多公斤生产所有步骤的优化。
