3-Hydroxybenzyl alcohol (3.0 g, 24.6 mmol) was dissolved in 1,3-dimethyl-2-imidazolidinone (50 mL). 4-Bromofluorobenzene (6.5 g, 36.9 mmol), potassium carbonate (2.0 g, 14.8 mmol), 8-quinolinol (71 mg, 0.5 mmol), and copper chloride(I) (49 mg, 0.5 mmol) were added thereto, and then the mixture was stirred at 150° C. for 2 days. To the reaction solution was added water, and the reaction mixture was extracted with ethyl acetate. The extract was dried, and then concentrated under reduced pressure. The residue was purified with silica gel column chromatography (hexane/ethyl acetate=90:10 to 80:20) to give the title compound (0.98 mg, yield 18%).
