Reaction Steps
4-Fluorobenzaldehyde (9.61 g, 80.0 mmol) in tetrahydrofuran (120 mL) was mixed with ethyl 2-(diethoxyphosphoryl)acetate (17.9 g, 80.0 mmol) under cooling with ice, and then sodium ethoxide-ethanol solution (21 wt %, 44.8 mL, 120 mmol) was added dropwise to the reaction mixture under cooling with ice, and the resulting reaction mixture was stirred at room temperature for 2 hours. After addition of water, the reaction mixture was extracted with ethyl acetate, and the organic layer dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=20/1→10/1 (v/v)) to give the title compound as a colorless oil (14.1 g, yield 91%).
