18.27 g of benzylamine were dissolved in 100 ml of methylene chloride and, while cooling with ice, 6.00 ml of methanesulfonyl chloride were very slowly added dropwise. On completion of addition of the methanesulfonyl chloride, the reaction solution was diluted with 100 ml of water, and the aqueous phase was extracted again with 50 ml of methylene chloride. The combined organic phases were washed with 1 N aqueous hydrochloric acid, dried over MgSO4 and concentrated by rotary evaporation. This gave the product (14.40 g) with a molecular weight of 185.3 g/mol (C8H11NO2S).
