实验步骤: After methanesulfonyl chloride (12.7 g) was added to a solution of N-(2-hydroxyethyl)phthalimide (19.1 g) in anhydrous dichloromethane (200 ml), triethylamine (20 ml) was added dropwise to the mixture in an ice bath. The mixture was stirred at ambient temperature for 4 hours. At the end of this time the reaction mixture was concentrated under reduced pressure. The residual solid was washed with ethyl acetate and water and then recrystallized from ethyl acetate to afford the desired compound (18.2 g). was added dropwise to the mixture in an ice bath At the end of this time the reaction mixture was concentrated under reduced pressure The residual solid was washed with ethyl acetate and water recrystallized from ethyl acetate
