Ethyl Acetate → 4-(5,5-Dimethyl-3-naphthylcarbonyl-2,4-dioxoimidazolidinylmethyl)benzonitrile

Participants

Reaction Steps

5,5-Dimethyl-3-naphthylcarbonylimidazolidine -2,4-dione (35 mg) was dissolved in DMF (0.4 mL) and sodium hydride (60%, in oil) (5 mg) was added. Then, 4-cyanobenzyl bromide (25 mg) was added, and the mixture was stirred at room temperature overnight. Ethyl acetate (9.5 mL) was added to the reaction solution, separated out white precipitates were filtered, and the filtrate was concentrated and purified by silica gel chromatography (hexane:ethyl acetate=2:1) to obtain 24 mg of white crystals.
