反应详情

A solution of benzenesulfonylchloride (10 ml; 78 mmol) in THF (100 ml) was added a 40% solution of dimethylamine in H2O (20 ml; 160 mmol) such that the reaction temperature was kept below 50° C. The reaction mixture was stirred 1 h at rt. The reaction mixture was added H2O and THF removed by evaporation. The precipitate formed was isolated by filtration and air dried to give 14 g (97%) of N,N-dimethylbenzenesulfonamide.
