50 ml of acetone was added to 3.3 g of N-hydroxyphthalimide and 4.1 g of p-styrenesulfonyl chloride. 2.0 g of triethylamine was dropwise added to the mixture under stirring at room temperature (about 20° C.). The mixture was stirred at room temperature for additional 1 hr. and poured into 200 g of ice/water. The precipitate thus formed was recrystallized from a solvent mixture of benzene/ethanol to obtain 4.6 g of N-hydroxyphthalimide-p-styrenesulfonate.
