実験手順

A mixture of Example 1e (1.33 g, 3.5 mmol), 5-(ethoxycarbonyl)-2-fluorophenylboronic acid (1.04 g, 4.9 mmol), Pd(PPh3)4 (0.20 g, 5 mol %), and sodium carbonate (0.742 g, 7.0 mmol) in toluene (12 mL), ethanol (3 mL) and water (3 mL) was degassed and stirred under a nitrogen atmosphere. The reaction mixture was heated at 90° C. for 24 hours. The reaction mixture was cooled to room temperature and partitioned between water and ethyl acetate. The aqueous layer was extracted with additional ethyl acetate twice. The combined organic layers were washed with brine, dried over MgSO4, filtered, and concentrated. The residue was purified by flash chromatography (silica gel, 20-50% ethyl acetate in hexanes) to afford 1.43 g (87%) of the title compound.
