Procedure

1.04 g (5.77 mmol) of m-(methoxycarbonyl)phenyl boronic acid, 1.00 g (3.67 mmol) of quinolin-8-yl trifluoro-methanesulfonate, 125 mg (0.11 mmol) of tetrakis(triphenylphosphine)palladium(0), and 611 mg (5.77 mmol) of sodium carbonate were heated under reflux in a mixed solvent comprising 4 mL of H2O, 23 mL of toluene, and 6.7 mL of methanol for 20 hours. After the completion of the reaction, the organic solvent was distilled off under reduced pressure, H2O was added to the residue, and ethyl acetate extraction was performed. Subsequently, the organic layer was washed with saturated saline and dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure. The obtained crude product was separated and purified by silica gel column chromatography, thereby giving 820 mg of methyl 3-(quinolin-8-yl)benzoate (yield: 86%).
