Participants

Procedure

Sodium hydride (80 mg) was added to a solution of benzyl 4-(2-oxoimidazolidin-1-yl)piperidin-1-carboxylate (0.30 g) in DMF (5 mL), the mixture was stirred at room temperature for 30 minutes. After addition of methyl iodide (0.25 mL), the mixture was stirred at room temperature for 15 hours. The reaction mixture was concentrated under reduced pressure, diluted with water, and extracted with ethyl acetate. The extract was washed with water, an aqueous 5% citric acid solution and saturated saline solution and dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure to obtain the title compound (0.32 g, quantitative) as a colorless oil.
