Water → 3-Benzyloxymethyl-5-methylimidazolidine-2,4-dione

Participants

Reaction Steps

5-Methylimidazolidine-2,4-dione (1.00 g) was dissolved in N,N-dimethylformamide (20 mL), potassium tert-butoxide (1.08 g) and benzyl chloromethyl ether (1.32 mL) were added under ice-cooling, and the mixture was stirred at room temperature for 5 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and the solvent was evaporated. The obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate) to give the title compound (0.98 g).
