LiOH (0.21 mg, 8.9 mmol) in a mixture ethanol/water 2/1 (18 ml) was added to a solution of N-(2-iodo-4-nitrophenyl)-N-(methylsulfonyl)methanesulfonamide (0.75 g, 1.78 mmol). The reaction mixture was refluxed for two hours. After cooling at room temperature, the reaction mixture was neutralized with H2O, NH4Cl and HCl 2N, then ethanol was eliminated, and the aqueous phase was extracted with ethyl acetate (3×20 ml). The organic solvent was removed by evaporating under reduced pressure to give N-(2-iodo-4-nitrophenyl)methanesulfonamide without further purification.
