Procedure

To 100 mL of thionyl chloride at 0° C. is added 25.1 g (0.1 mol) of 4-[(ethylsulfonyl)amino]benzoic acid sodium salt (prepared from the acid and sodium hydroxide in water and evaporation of solvent) under a nitrogen atmosphere. Reflux the reaction mixture for 24-40 hr. then remove the excess thionyl chloride in vacuo. Dissolve the crude material in tetrahydrofuran, filter through celite and evaporate the solvent to obtain the title compound.
