Methyl 2-,3-,4-carboxyphenylacetate and methyl 2-,3-,4-carboxyphenoxyacetate have been prepared through selective esterification of the aliphatic carboxylic acid function of the corresponding dicarboxylic acids using a mixture of phosphorus pentoxide (1 part), anhydrous copper sulphate (5 parts) and anhydrous sodium sulphate (5 parts).All the isomeric half-esters have been prepared through partial hydrolysis of the corresponding dimethylesters.
