실험 절차

A solution of diethyl 2-(6-heptenyl)malonate (3.83 g, 14.92 mmol) in anhydrous tetrahydrofuran (50 ml) was slowly added dropwise to a suspension of 60% sodium hydride (0.52 g, 12.94 mmol) in anhydrous tetrahydrofuran (150 ml) at 0° C., and the resulting mixture was stirred for 1 hour. The 1-iodo-5,5,6,6,7,7,8,8,8-nonafluorooctane prepared in Example 2 (4.0 g, 9.95 mmol) was dissolved in anhydrous tetrahydrofuran (50 ml) and then slowly added dropwise to the mixture, followed by stirring for 2 days at room temperature. After the reaction was completed, water was added to the reaction mixture, which was then extracted twice with ethyl acetate. The combined organic layers were washed with water and saturated aqueous sodium chloride, and then dried over anhydrous magnesium sulfate. After distilling off the solvent, the residue was purified by silica gel column chromatography (eluent: ethyl acetate/hexane=1/30) to give diethyl 2-(6-heptenyl)-2-(5,5,6,6,7,7,8,8,8-nonafluorooctyl)malonate (4.7 g, Yield 89%).
