Reaction Steps

1.0 g (2.7 mmol) of methyl 2-(N-tert-butylsulfamoyl)-4-(2-isobutyrylhydrazino)benzoate is stirred in 10 ml of trifluoroacetic acid at 25° C. for 2 hours. The mixture is evaporated and the residue is triturated with diethyl ether. Filtration with suction and drying gives 0.8 g (94% of theory) of methyl 4-(2-isobutyrylhydrazino)-2-sulfamoylbenzoate of melting point 198°-200° C.
