Dimethylamine → 2-cyano-N,N-dimethylbenzenesulfonamide

Participants

Reaction Steps

A solution of 2-cyanobenzensulfonylchloride (2.0 g, 10 mmol), dimethyl amine (1.18 g, 10 mmol, 40 wt % in water) and triethylamine (1.5 mL, 10 mmol) were stirred together at room temperature for 30 min. The resulting slurry was diluted with ethyl acetate and filtered. The filter cake was washed with ethyl acetate and the combined filterate was washed with water, dried (Na2SO4) and concentrated to give the title product as orange plates (1.78 g, 85% yield). 1HNMR (300 MHz, CDCl3) δ: 8.02 (1H, dd, J=8.05, 1.46 Hz), 7.87 (1H, dd, J=7.32, 1.47 Hz), 7.79–7.76 (2H, m), 2.86 (6H, s). LCMS calcd for C9H11N2O2S (M+H): 211.05; found: 211.09.
