Procedure

By substituting ethyl-4-phenoxy-3-propargylamino-5-sulphamyl-benzoate for the ethyl-3-allylamino-4-phenoxy-5-sulphamyl-benzoate of Example 58 B and by recrystallizing from dilute ethanol, 4-phenoxy-3-propargylamino-5sulphamyl-benzoic acid was obtained with a melting point of 222°-223° C.
