Under a nitrogen atmosphere, to a mixed solvent of the compound (270 mg, 0.72 mmol) obtained in Example 190c, 3-fluoro-4-methoxycarbonylphenylboronic acid (170 mg, 0.86 mmol) and cesium carbonate (1.2 g, 3.6 mmol) in tetrahydrofuran-water (v/v=5/1, 6 mL) was added [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) dichloromethane complex (120 mg, 0.14 mmol), and the mixture was stirred at 90° C. overnight. The resulting salt was filtered and removed, and the solvent was evaporated under reduced pressure. The obtained crude product was purified by column chromatography (hexane-hexane/ethyl acetate=75/25) to give the title compound as colorless crystals.
