Procedure

A solution of dimethylamine in tetrahydrofuran (2M, excess) was added 4-(4-chlorosulfonylbenzyl)-nitrobenzene dichloromethane hemisolvate (354 mg, 1 mmol) dissolved in tetrahydrofuran (5 mL). The mixture was stirred for 1 hour and extracted with a solution of diethyl ether and dilute potassium carbonate. The organic layer was separated and solvents evaporated. The residue was recrystallized from acetone/hexanes to give 4-(4-dimethylaminosulfonylbenzyl)-nitrobenzene (311 mg, 98%).
