The Synthesis of Ortho-Substituted 2-Diethylaminoethyl Benzoates as Potential Local Anaesthetics

Abstract

A series of mono‐ortho‐ and di‐ortho‐ substituted benzoic esters of 2‐diethylaminoethanol has been synthesised. Improved methods for the preparation of 2,6‐difluorobenzoic acid and 2,6‐dimethylbenzoic acid are reported. The preparation of esters of di‐ortho‐ substituted benzoic acids is discussed and an efficient method of esterification of these acids is described.
