실험 절차

To a stirring solution of N-(5-chloropyridin-2-yl)-5-iodo-2-[(1-isopropylpiperidin-4-ylcarbonyl)amino]benzamide (1.0 g, 1.90 mmol) in N-methyl-2-pyrrolidinone (25 mL) was added tetrakis(triphenylphosphine)palladium(0) (0.12 g, 0.1 mmol), triphenylarsine (60 mg, 0.2 mmol) and copper iodide (10 mg, 0.05 mmol) followed by tributyl(vinyl)tin (0.63 mL, 2.09 mmol). The reaction solution was heated to 105° C., stirred for 8 h, partitioned between dichloromethane and saturated aqueous sodium bicarbonate, and the layers separated. The organic phase was washed with brine, dried over magnesium sulfate, filtered, and concentrated in vacuo. The crude product was purified by chromatography over silica gel, eluting with 10% 2 M ammonia/methanol solution in dichloromethane. The chromatography product was slurried in methanol and filtered to give 131 mg (16%) of a white solid.
