실험 절차

To a solution of 3-bromo-4-chloro-N-{(3RS,4SR)-4-(3,4-dichloro-phenyl)-1-[1-(1-methyl-cyclopropanecarbonyl)-piperidine-4-carbonyl]-pyrrolidin-3-yl}-N-methyl-benzamide (50 mg; 0.076 mmol) in THF (0.5 mL) was added under an argon atmosphere tetrakis(triphenylphosphine)palladium (0) (5 mg; 0.04 mmol) and diethylzinc (1 M in hexane, 762 μL; 0.762 mmol). The resulting solution was stirred for 5 h at 65° C. before it was diluted with ethyl acetatec (30 mL) and washed with aqueous sodium carbonate (saturated, 20 mL), water (20 mL) and aqueous sodium carbonate. (saturated, 20 mL). The aqueous phases were extracted with ethyl acetate (30 mL) and dried over sodium sulfate. Purification by chromatography (SiO2, ethyl acetate:methanol=100:0 to 90:10) afforded the title compound (37 mg, 47%) as a light brown foam. MS m/e: 604.2 [M]+.
