4-Bromo-1-indanone (600 mg, 2.84 mmol) was dissolved in toluene (10 mL), and ethyl boronate (105 mg, 8.52 mmol), silver oxide (I) (274 mg, 7.10 mmol), potassium carbonate (196 mg, 8.52 mmol), and a [1,1′-bis(diphenylphosphino)ferrocene]palladium(II) dichloride dichloromethane complex (46 mg, 0.0568 mmol) were added thereto, and then, the resulting mixture was heated to reflux under a nitrogen atmosphere at 100° C. for 4 hours. After cooling to room temperature, the reaction solution was filtered, and the solvent was distilled off, whereby a crude product was obtained. This crude product was purified by silica gel column chromatography (hexane:ethyl acetate=100:0 to 80:20 (v/v)), whereby the title compound was obtained as a colorless oily substance (421 mg, yield: 92%).
