摘要:
Described is a process for the preparation of compounds of formula (1a) which comprises reacting an isomeric mixture consisting of from 75 to 95% of compound of formula (2a) and from 5 to 25% of a compound of formula (2b) with methylamine, in a suitable solvent, to form a sertraline-imine isomeric mixture consisting of from 75 to 95% of formula (1a) and from 5 to 25% of formula (1b)(A1), or reacting an isomeric mixture consisting of from 75 to 95% of a compound of formula (2a) and from 5 to 25% of a compound of formula (2b) with methylamine, in a suitable solvent, using suitable methods of isolation to form an enriched sertraline-imine isomeric mixture, consisting of >99% of a compound of formula (1a) and
