PROCESS FOR CONVERTING A CIS-TRANS MIXTURE OF SUBSTITUTED BENZYLIDENE AMINES INTO THE PURE CIS ISOMER

摘要

A process for interconverting a mixture of cis-trans erythro-threo isomers o f a compound of formula I into the substantially pure cis isomer. Cis isomers of formula I are usefull intermediates in the synthesis of cis isomers of benzamide piperidine compounds which exhibit activity as NK-1 receptor antagonists.
