Reaction Steps

To a solution of N-[1-dimethylamino-methylidene]-2-nitro-6-methoxy-benzenesulfonamide (956 mg, 3.33 mmol) in dichloromethane (50 mL) BBr3 (0.64 mL, 6.64 mmol is added under stirring at room temperature. After stirring for 30 min the 4 mixture is diluted with CH2Cl2 and extracted twice with saturated brine. Drying of the organic phase with Na2SO4, evaporation of solvent, addition of hexanes to the residue, and filtration gives N-(1-dimethylamino-methylidene)-2-nitro-6-hydroxy-benzenesulfonamide.
