Procedure

A 15 mL round bottom flask was charged with (+)-(4aR)-(10bR)-8-(4-nitro-2-trifluoromethylphenyl)-10b-methyl-1,2,3,4,4a,5,6,10b-octahydrobenzo[f]quinolin-3-one (48 mg, 0.12 mmol), 0.3 mL of t-butanol, and potassium t-butoxide (40 mg, 0.36 mmol). Methyl iodide (0.022 mL, 0.36 mmol) was added and the mixture was stirred at room temperature for 4 h. The mixture was diluted with ethyl acetate, and purified by silica gel chromatography (ethyl acetate eluent) to give 35 mg (70%) of the title compound as a white solid. mp 128°-130°. FDMS: m/e=418.
