The present invention relates to an improved process for the preparation of N-((1R,2R)-1-(2,3- dihydrobenzo[b][1,4]dioxin-6-yl)-1-hydroxy-3-(pyrrolidin-1-yl)propan-2-yl)octanamide (A), which is known as ELIGLUSTAT and its pharmaceutically acceptable salts, comprising the formation of novel intermediate metal complex (III), which on hydrolysis in presence of acid provides amine compound (IV) (as described herein), which is treated with pyrrolidine and subsequently reduced to convert into Eliglustat (A).
本发明涉及一种改进的制备N-((1R,2R)-1-(2,3-二氢苯并[b][1,4]二氧杂环己烯-6-基)-1-羟基-3-(吡咯烷-1-基)丙烷-2-基)辛酰胺(称为ELIGLUSTAT)及其药用可接受的盐的方法,包括形成新型中间体金属络合物(III),在酸的存在下水解形成胺化合物(IV)(如本文所述),该化合物经吡咯烷处理,随后还原转化为Eliglustat(A)。
