Participants

Reaction Steps

3 g of methyl (S)-(4-(4-cyanophenyl)-4-methyl-2,5-dioxoimidazolidin-1-yl)acetate (10.4 mmol) were dissolved in 15 ml of anhydrous dimethylformamide under argon. 11.4 mmol of sodium hydride in the form of a dispersion in mineral oil were added in an argon countercurrent. The reaction mixture was stirred at room temperature for 15 minutes. It was then treated with 721 μl of methyl iodide (11.4 mmol). The mixture was stirred at room temperature for 4 hours and then allowed to stand at room temperature overnight. The solution was concentrated. For purification, the substance was chromatographed on silica gel using methylene chloride/ethyl acetate (9.5:0.5). The fractions containing the pure substance were concentrated.
