実験手順

1.00 g (4.65 mmol) of methyl 3-bromobenzoate, 0.60 g (4.88 mmol) of phenylboronic acid, 161 mg (3 molar %) of tetrakistriphenylphosphine palladium and 2.0 g (18.6 mmol) of sodium carbonate were heated under reflux in 24 ml of a solvent mixture of toluene, ethanol and water (2/1/1) for 2 hours. The mixture was filtered through Celite, then after-treated by an ordinary method and purified by the silica gel column chromatography to obtain the title compound.
