Procedure

To a solution of 2.14 g of benzylamine in 10 ml of ether at 5° C. was slowly added a solution of 1.37 g of cyanomethylsulfonylchloride [Sammes, et al., J. Chem. Soc. (C), 2151, 1971] in 5 ml of ether. The resulting mixture was then stirred for another 30 minutes, poured into 50 ml of water and extracted with 50 ml of ethyl acetate. The organic layer was then washed with brine, dried over magnesium sulfate, filtered and concentrated. The crude sulfonamide was then purified on a silica gel column (1:1 hexane/ethyl acetate) to provide 1.52 g of N-benzyl cyanomethylsulfonamide.
