Procedure
To a mixture of 24.93 g (0.10 mol) of N-phenyl-4-hydroxybenzenesulfonamide, 10.12 g (0.10 mol) of triethylamine and 150 ml of methylene chloride was added, dropwise, a solution of 24.75 g (0.10 mol) of 4-(2-bromoethyl)benzoyl chloride in 150 ml of methylene chloride over a period of 12 minutes. The reaction mixture was stirred at room temperature for 3 hours, after which 500 ml of methylene chloride were added. The solution was washed once with 2% HCl and twice with water, dried over magnesium sulfate and concentrated to a white solid. Recrystallization from ethanol gave 39.7 g (86.1% of theory) of 4-(N-phenylsulfamoyl)phenyl 4-(2-bromoethyl)benzoate, mp=156°-7° C.
