Acetonitrile → N-(1,1-Dimethylethyl)benzenesulfonamide

참여 물질

반응 단계

To a solution of benzenesulfonyl chloride (722 μL, 0.00566 mol), potassium carbonate (0.939 g, 0.00679 mol) in acetonitrile (15 mL, 0.29 mol) was added tert-butylamine (0.652 mL, 0.00623 mol). The resulting mixture was stirred at r.t. for 30 minutes, followed by filtration and concentration. The resulting residue was diluted with ethyl acetate, and the resulting solution was washed with water then with brine, then dried with MgSO4 followed by concentration. The crude material was purified by flash chromatography on silica gel with 40% AcOEt in hexanes to give the desired compound (1.21 g, 85% yield). MS (ESI): 236.0 (M+Na+).
