Procedure

A 15 mL round bottom flask was charged with (+)-(4aR)-(10bR)-4-methyl-8-mercapto-10b-methyl-1,2,3,4,4a,-5,6,10b-octahydrobenzo[f]quinolin-3-one (86 mg, 0.33 mmol), potassium carbonate (158 mg, 1.14 mmol), 1-chloro-3-phenyl-isoquinoline (95 mg, 0.40 mmol) and 1 mL of anhydrous dimethylformamide, fitted with a reflux condenser, and the stirred mixture was heated at 60°, under nitrogen, for 18 h. The mixture was cooled, diluted with ethyl acetate (75 mL) and washed with brine (2×25 mL). The combined organic extracts were dried over sodium sulfate, concentrated, and purified by silica gel chromatography (80% ethyl acetate/hexanes eluent) to give 64 mg (42%) of the title compound as an off white solid. mp 183°-189°. FDMS: m/e=464. α[D]589 =+54.61 (c=0.53, chloroform).
