Yield:-

Reaction Conditions:

with methylamine in dichloromethane

Steps:

1.a a
The organic layer was separated, dried over anhydrous sodium sulphate, filtered and evaporated to give 4-nitrobenzyl sulphonyl chloride (48.9 g, 83%) which was pure by ¹ H NMR. Methylamine gas was bubbled through a solution of 4-nitrobenzyl sulphonyl chloride (37.9 g, 0.16 mol), in dichloromethane (325 ml), until uptake had ceased (0.5 h). The resulting solid was filtered, washed with H₂ and dried under vacuum to give the title-sulphonamide (32.5 g, 88%), δ(250MHz, D₆ -DMSO) 2.61 (3H, s, Me), 4.55 (2H, s, CH₂), 7.06 (1H, s, NH), 7.66 (2H, d, J=8.7Hz, Ar-H), 8.25 (2H, d, J=8.7Hz, Ar-H).
