Reaction Steps

3,5-Dichlorophenol (500 mg, 3.07 mmol) was dissolved in dimethylacetamide (8.0 mL), and 4-fluorobenzaldehyde (0.390 mL, 0.368 mmol) and cesium carbonate (1.50 g, 3.69 mmol) were sequentially added thereto at room temperature, and then, the resulting mixture was stirred under a nitrogen atmosphere at 150° C. for 3 hours. After the temperature of the reaction solution was returned to room temperature, water was added thereto, and the organic matter was extracted with ethyl acetate. The organic layer was washed with a saturated aqueous solution of ammonium chloride and a saturated sodium chloride solution, then dried over anhydrous sodium sulfate and filtered. Then, the solvent was distilled off under reduced pressure, whereby a crude product was obtained. This crude product was purified by silica gel column chromatography (hexane:ethyl acetate=100:0 to 85:15 (v/v)), whereby the objective title compound was obtained as a white solid (364 mg, yield: 44%).
