Procedure

A 15 mL round bottom flask was charged with (+)-(4aR)-(10bR)-8-bromo-10b-methyl-1,2,3,4,4a,5,6,10b-octahydrobenzo[f]quinolin-3-one (500 mg, 1.70 mmol), tetrakis(triphenylphosphine)palladium(0) (80 mg, 0.07 mmol), 1-napthylboronic acid (439 mg, 2.55 mmol), 2.4 mL of 2M sodium carbonate and 4 mL of toluene, fitted with a reflux condenser, and the stirred mixture was heated at 80°, under nitrogen, for 24 h. The mixture was cooled, diluted with dichloromethane (200 mL) and washed with brine (2×50 mL). The combined organic extracts were dried over sodium sulfate, concentrated, and purified by silica gel chromatography (0-50% methanol/ethyl acetate eluent gradient) to give 405 mg (70%) of the title compound as a white solid. mp 247°-248°. FDMS: m/e=341. α[D]589 =+1.93 (c=1.04, methanol).
