Abstract
A method for the industrial production of 3,5-dimethylbenzoic acid derivatives and their salts by the addition of acids, of the general formula ** (see formula) ** Wherein x is a heteroatom, such as oxygen, nitrogen or sulfur and y an ethyl chain with a disubstituted amino group at position two, based on the reaction of activated derivatives of the acid with the corresponding derivative of the substituted ethylamine, within the an appropriate solvent and treating the obtained product with a base, extracting with a suitable solvent, drying, eliminating the solvent and distilling or crystallizing the residual product.
