Reaction Steps

At room temperature, 19.6 g (0.055 mol) of methyl 2-tert-butylsulfamoyl-4-isopropylcarbamoylbenzoate were stirred in 200 ml of trifluoroacetic acid for 3 h. The mixture was concentrated and the residue was triturated with diethyl ether and filtered off. This gave 15.6 g (95% of theory) of methyl 4-isopropylcarbamoyl-2-sulfamoylbenzoate of m.p. 203-205° C.
