To a mixture of 2-methoxy-6-(4-methoxyphenyl)-1-bromonaphthalene (0.80 g, 2.33 mmol) and tetrakis(triphenylphosphine)palladium (0.13 g, 0.12 mmol) in THF (10 mL) was added phenylmagnesiumbromide (2.2 mL of 3 N in ether). The reaction mixture was stirred at reflux overnight, cooled to room temperature, poured into 1 N HCl (100 mL), and extracted with ethyl acetate (3×200 mL). The combined organic layers were washed with sodium bicarbonate solution, dried over magnesium sulfate, filtered, evaportation of the solvent, and purification by silica column chromatography (10% ethyl acetate-hexanes) yielded 0.42 g (53%) of a gray solid: mp 157-160° C.; 1H NMR (CDCl3): δ 3.85 (3H, s), 3.87 (3H, s), 7.01 (2H, d, J=8.64 Hz), 7.38-7.46 (4H, m), 7.49-7.57 (4H, m), 7.64 (2H, d, J=8.64 Hz), 7.92 (1H, d, J=9.05 Hz), 7.97 (1H, s); MS (ESI) m/z 341 (M+H)+.
