Procedure
A mixture of 3 -amino-4-anilino-5-sulphamyl-benzoic acid (2 g), benzyl bromide (3 g), and ethanol (50 ml 99.9%) was refluxed for 8 hours. After cooling, the ethyl-4-anilino-3-benzylamino-5-sulphamyl-benzoate crystallized and was collected by suction. After recrystallization from ethanol the melting point was 160°-161° C.
