Procedure

3-Naphthylcarbonyl-5,5-diphenylimidazolidine-2,4-dione (406 mg) was dissolved in dimethylformamide (DMF: 2 mL), ethyl bromoacetate (167 mg) was added, and potassium carbonate (138 mg) was further added. The reaction solution was stirred at room temperature overnight. After water was added carefully, ethyl acetate (100 mL) was added, followed by extraction. The resulting organic layer was washed with a saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was distilled off. Recrystallization from methanol afforded 338 mg of white crystals.
