An improved method for the preparation of 6-sulfamoylsaccharin (3-oxo-2,3-dihydro-1,2-benzo-thiazole-6-sulfonamide 1,1-dioxide) has been developed and studies of its possible direct alkylation have been carried out. It was shown that alkylation occurs regioselectively at the isothiazoline ring nitrogen atom.
