Procedure

3-Naphthylcarbonyl-5,5-diphenylimidazolidine-2,4-dione (879 mg) was dissolved in DMF (3 mL), tert-butyl bromoacetate (421 mg) was added, and potassium carbonate (299 mg) was further added. The reaction solution was stirred at room temperature overnight. After water was carefully added, ethyl acetate (200 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. Further, recrystallization from methanol afforded 846 mg of white crystals.
