In a process for preparing an N-(alkanoyl)aminoalkanoyloxy benzenesulfonate by reacting acetoxy benzene sulfonate with an amido carboxylic acid, the improvement which comprises conducting the reaction in the presence of at least about 0.1 mole equivalent based on the amido carboxylic acid of a tertiary amine selected from the group consisting of tris[2-(2-methoxyethoxy)ethyl)amine, N,N-dimethyldodecylamine, imidazole and mixtures thereof.
In a process for preparing an N-(alkanoyl)aminoalkanoyloxy benzenesulfonate by reacting acetoxy benzene sulfonate with an amido carboxylic acid, the improvement which comprises conducting the reaction in the presence of an amido solvent selected from the group consisting of cyclic amides, N-substituted imides, urea derivatives and mixtures thereof.
