反応手順
Under an argon atmosphere, 18.7 g of 3-bromoanisole, 23.8 g of 2-biphenylboronic acid and 2.31 g of tetraxis(triphenylphosphine)palladium(0) were placed in a flask. 340 mL of dimethyl ether (DME) and 170 mL of a 2M aqueous sodium carbonate solution were added to this flask, and the resultant was refluxed with stirring while heating for 8 hours. After cooling to room temperature, an aqueous phase was removed. An organic phase was washed with water and saturated brine, and then dried with magnesium sulfate. After the magnesium sulfate was filtered out, the organic phase was concentrated. The resulting residue was purified by means of silica gel column chromatography, whereby 23.4 g (yield: 90%) of intended 3-methoxy[1,1′:2′,1″]terphenyl was obtained.
