Versuchsvorschrift
A solution of ethyl-4-anilino-3-benzylamino-5-phenylsulphamyl-benzoate (3 g) in 1N sodium hydroxide (30 ml) was heated on a steam bath for 1 hour. The 4-anilino-3-benzylamino-5-phenylsulphamyl-benzoic acid was precipitated by addition of 4N hydrochloric acid until pH 2, and recrystallized from acetone-water and 80% ethanol in water; the melting point was 243° C.
