Procedure: The product so obtained was used in place of 4-iodoaniline in the procedure described in Example 3 for the preparation of N-(4-iodophenyl) methanesulphonamide and ethanesulphonyl chloride was used in place of methanesulphonyl chloride. Thus was obtained N-(4-iodophenyl)-N-methylethanesulphonamide as an oil. NMR Spectrum 1.45 (3H, t), 3.00 (2H, q), 3.35 (3H, s), 7.15 (2H, m), 7.70 (2H, m). The product so obtained

Procedure: A mixture of N-(4-iodophenyl)methanesulphonamide (4.3 g), 50% aqueous sodium hydroxide (25 ml), iodomethane (5 ml), dichloromethane (10 ml) and tetrabutylammonium bisulphate (0.5 g) was stirred vigorously for 2 h. Water (50 ml) was added and the mixture was extracted with ether (3×50 ml). The organic extracts were washed with water and brine, dried and concentrated to a solid which was triturated with hexane to give the title compound as white crystals (4.1 g) m.p. 106°-107°. the mixture was extracted with ether (3×50 ml) The organic extracts were washed with water and brine dried concentrated to a solid which was triturated with hexane
