실험 절차

Diethyl 2-acetamidomalonate (3.0 g) was dissolved in 50 ml of dry ethanol and 1.13 g of sodium ethoxide was added thereto. A solution of 4.7 g of tetradecyl bromide in 20 ml of ethanol was added to the mixed solution while stirring at room temperature. The inside of the reaction vessel was displaced with nitrogen and the mixture was refluxed for about 15 hours. Then, the mixture was neutralized with a 1 N aqueous hydrochloric acid solution and concentrated. The concentrate was purified by silica gel column chromatography to give 3.5 g of diethyl 2-acetamido-2-tetradecylmalonate.
