Process for the synthesis of esters of parachlorobenzoyl-phenoxy-isobutyric acid.

摘要

1. A process for manufacturing methyl ester of 4-(parachlorobenzoyl)-phenoxyisobutyric acid, characterized in that a so-called PERKIN reaction is carried out between parachlorobenzoic anhydride and the methyl ester of phenoxyisobutyric acid, said reaction being carried out within a solvent using BF3 as a catalyst and by operating at a temperature close to ambiant temperature.
