실험 절차

0.15 g of 60% sodium hydride was suspended in 20 ml of N,N-dimethylformamide, to which 1.15 g of N-(diethoxyphosphoryl)acetylpiperidine was gradually added at room temperature. After stirring for 10 minutes, a solution of 800 mg of 5-ethyl-3-methoxy-4-methoxymethoxy-1-naphthalenecarbaldehyde in N,N-dimethylformamide (10 ml) was gradually added. After stirring for 20 minutes, water was added, followed by extraction with ethyl acetate. The combined extracts were washed with water and dried over anhydrous magnesium sulfate. After removal of the solvent, the resultant residue was purified by silica gel column chromatography (30% ethyl acetate/hexane) to obtain 1.1 g of the titled compound as pale yellow crystals.
