Reaction Steps

3-Allylthio-5-chlorosulfonyl-4-phenoxybenzoic acid (1 g) is dissolved in cooled concentrated aqueous ammonia (20 ml) while stirring. After 1 hour the reaction mixture is heated on a steam bath for 5 minutes, cooled, and 3-allylthio-4-phenoxy-5-sulfamylbenzoic acid precipitated by addition of 4 N hydrochloric acid. After collection by filtration, recrystallisation from aqueous ethanol, and drying, the compound is obtained with a melting point of 218°-219°C.
