Reaction Steps
Ethyl 3-benzylamino-5 -dimethylsulphamyl-4-phenoxy-benzoate (1 g) was heated on a steam bath with 1N sodium hydroxide (15ml) for 6 hours. From the resulting solution, the 3-benzylamino-5-dimethylsulphamyl-4-phenoxy-benzoic acid was precipitated by addition of 4N hydrochloric acid until a pH of 2.5. After isolating and recrystallizing from aqueous ethanol, the compound was obtained with a melting point of 205°-206° C.
