  • Process for the preparation of 5-cyanophthalide starting from 5-carboxyphthalide
    申请人:Adorkem Technology SpA
    公开号:EP1777221A1
    公开(公告)日:2007-04-25
    A new process is clescribed for obtaining 5-cyanophthalide, which is an intermediate used for the synthesis of citalopram and its active enantiomer S(+) citalopram, both of which are known active ingredients commonly used for treating depression. The process starts from 5-carboxyphthalide which is converted into the corresponding acylochloride. The latter is reacted with hydroxylamine to give the corresponding hydroxamyl phthalide which is subsequently subjected to a dehydration reaction to give 5-cyanophthalide.
