Dimethylamine → N,N-dimethyl-4-nitrobenzenesulfonamide

Participants

Reaction Steps

To the solution of dimethylamine (284 mg, 6.3 mmol, 1.5 equiv.) and DIPEA (1 mL) in DCM (15 mL) was added dropwise a solution of 4-nitrobenzene-1-sulfonyl chloride (800 mg, 4.2 mmol, 1.0 equiv.) in DCM (5 mL). The reaction mixture was stirred at room temperature for 2 h. Then, the reaction mixture was washed with water and brine. The organic layers was dried (Na2SO4) and concentrated to get the residue, which was washed with isopropyl ether to afford compound N,N-dimethyl-4-nitrobenzenesulfonamide (879 mg, 91%).
