Participants

Reaction Steps

150 mg of (S)-1-(3,4-Dichlorophenyl)-4-hydroxymethyl-4-phenylimidazolidine-2,5-dione are dissolved in 5 mL of dimethylformamide then 165 mg of potassium carbonate are added followed by 137 μL of dimethylsulfate. The mixture is stirred overnight at room temperature then it is taken in a mixture of water and ethyl acetate. The aqueous phase is extracted with ethyl acetate. The extracts are washed with brine, dried over magnesium sulfate and evaporated to dryness. The residue is purified over silica gel while eluting with a gradient mixture from heptane to pure ethyl acetate to provide the expected product.
