Reaction Steps

3-Naphthylcarbonyl-5,5-diphenylimidazolidine-2,4-dione (100 mg) was dissolved in DMF (4 mL), and sodium hydride (60%, in oil) (10 mg) was added at 0° C. under ice-cooling. After stirred for 30 minutes, methyl iodide (37 mg) was added at 0° C., and the mixture was stirred at room temperature overnight. Water (100 mL) was added to the reaction solution, and separated out white precipitates were filtered. Further recrystallization using hexane:ethyl acetate=1:1 afforded 64 mg of white crystals.
