실험 절차

To a mixture of 2-methoxy-6-(4-methoxyphenyl)-1-phenylnaphthalene (0.36 g, 1.06 mmol) in CH2Cl2 (25 mL) at 0° C. was slowly added boron tribromide (3.2 mL of 1 N in CH2Cl2). The mixture was allowed to warm slowly to room temperature and was stirred overnight. The resulting solution was poured into water (100 mL) and extracted with ethyl acetate (3×150 mL). The combined organic layers were washed with saturated sodium bicarbonate solution, dried over magnesium sulfate, evaporation of thesolvent, and purification by silica column chromatography (25% ethyl acetate-hexanes) followed by preparative reverse-phase HPLC and drying under vacuum at 105° C. yielded 0.14 g (42%) of the title compound as a white solid: mp 142-146° C.; 1H NMR (DMSO-d6): δ 6.86 (2H, d, J=8.50 Hz), 7.26-7.42 (5H, m), 7.48-7.61 (5H, m), 7.84 (1H, d, J=8.96 Hz), 8.02 (1H, d, J=1.46 Hz), 9.52 (2H, s); MS (ESI) m/z 311 (M−H)−.
