A solution of 0.6 ml of methanesulfonyl chloride in 3 ml of methylene chloride is added dropwise at 0° to a solution of 1.5 g (0.0075 mol) of N-(2-hydroxyethyl)-4-chlorobenzamide and 1 ml of triethylamine in 15 ml of methylene chloride. After 15 minutes, the mixture is poured on to ice/water and extracted. There are obtained 2.1 g of N-(2-methylsulfonyloxyethyl)-4-chlorobenzamide in crystalline form which is used in the next step without further purification.
