Reaction Steps

A mixture of 3-amino-5-sulphamyl-4-(m-toluidino)-benzoic acid (1.5 g), benzyl bromide (2.5 g), and anhydrous ethanol (50 ml) was heated under reflux for 10 hours. The resulting solution was cooled, and the precipated ethyl 3-benzylamino-5-sulphamyl-4-(m-toluidino)-benzoate was collected by suction. After recrystallization from ethanol, the compound had a melting point of 169°-170° C.
