摘要

氯化肉豆蔻基-γ-甲基吡啶(MGPC)是一种烷基吡啶季铵盐,也是 Depo-Medrol(醋酸甲泼尼龙)等注射剂中常用的防腐剂。在此,我们介绍了一种成功的高p,T,c 化学强化方法,即在连续流条件下,从纯肉豆蔻酰氯和 γ-甲基吡啶合成 MGPC。该工艺具有原子经济性、可扩展性和反应器占地面积小的特点,在优化的条件下,只需 45 分钟(而不是文献报道的传统间歇工艺的 8-12 小时)即可稳定地合成出 MGPC,并具有极佳的收率(90%)和纯度(99%)。

Investigation into a high-p,T,c continuous flow synthesis of myristyl-γ-picolinium chloride (MGPC) – a preservative in pharmaceutical formulations

Myristyl-γ-picolinium chloride (MGPC) is an alkyl pyridine quaternary ammonium salt and a popular preservative in injectables such as Depo-Medrol (Methylprednisolone acetate). Herein we describe a successful high-p,T,c chemical intensification of MGPC synthesis from neat myristyl chloride and γ-picoline in continuous flow. The process is atom economical, scalable with low reactor footprint and under optimized conditions, consistently affords MGPC in 45 min (instead of 8–12 h reported in literature for a conventional batch process) with excellent yield (> 90%) and purity (> 99%).
