Reaction Steps

At room temperature, 1.0 g (3.1 mmol) of N,N-dimethyl-2-tert-butylsulfamoyl-4-carbamoylbenzamide in 10 ml of trifluoroacetic acid was stirred for 2.5 h. The mixture was concentrated and the residue was triturated with diethyl ether, filtered off with suction and dried. This gave 0.53 g (63% of theory) of N,N-dimethyl-4-carbamoyl-2- sulfamoylbenzamide of m.p. 202-205° C.
