반응 단계
A solution of N-methyl-N-(3-tolyl)methanesulphonamide (0.12 g), iodine (76 g) and iodic acid (35 mg) in glacial acetic acid (5 ml) and concentrated sulphuric acid (0.6 ml) was stirred at 80° C. for 2.5 hours. Ethyl acetate (40 ml) and water (40 ml) were then added and the mixture neutralised with solid sodium bicarbonate. The organic phase was washed with brine (30 ml), dried (MgSO4) and the solvent evaporated to leave N-(4-iodo-3-methylphenyl)-N-methylmethanesulphonamide (0.22 g, 90%), m.p. 85°-87° C.
