Palladium diacetate (4.5 mg, 0.02 mmol), 1,4-(bisdiphenylphosphino)butane (8.5 mg, 0.02 mmol), triethylamine (55.8 μL, 0.4 mmol) and benzyl alcohol (1 mL) were added to a solution of methyl 4-bromo-2-fluorobenzoate (46.6 mg, 0.2 mmol) in dimethylformamide (1 mL). In this solution, bubbling was carried out for a few minutes with carbon monoxide, and then this solution was heated at 120° C. for 12 hours under carbon monoxide atmosphere. After completion of the reaction, ethyl acetate was added, and the resultant product was washed with a saturated ammonium chloride aqueous solution, and purified with a silica gel column chromatography (hexane/ethyl acetate=19/1) to obtain 35.4 mg of the desired product as a yellow viscous liquid (yield 61%).
