反応手順

To a solution of 2-iodo-4-nitroaniline (1.02 g, 3.86 mmol) in dichloromethane (10 ml), has been added under stirring triethylamine (1.77 ml, 12.7 mmol). To this mixture, a solution of methanesulphonyl chloride (0.98 ml, 12.7 mmol) in dichloromethane (2 ml) has been added dropwise, very slowly and in an ice-bath. The mixture so obtained was left under stirring at room temperature overnight. The day after, the reaction mixture was neutralized with a saturated aqueous solution of NH4Cl. The organic phase was separated, and, after evaporation of the solvent, the residue has been washed with ethanol and filtered to give N-(2-iodo-4-nitrophenyl)-N-(methylsulfonyl)-methanesulfonamide as yellow solid.
