Versuchsvorschrift

To a stirring solution of 2-[(1-tert-butoxycarbonylpiperidin-4-ylcarbonyl)amino]-N-(5-chloropyridin-2-yl)-5-iodobenzamide (0.51 g, 0.88 mmol) in N,N-dimethylformamide (13 mL) under argon was added dichlorobis(triphenyl-phosphine)palladium(II) (28 mg, 0.04 mmol) and triethylamine (0.5 mL, 3.5 mmol) followed by water (3 mL). The reaction mixture was evacuated and placed under an atmosphere of carbon monoxide, heated at 60° C. for 3 h., and concentrated in vacuo. The resulting residue was partitioned between aqueous sodium bicarbonate and ethyl acetate and the layers separated. The aqueous phase was treated with a small amount of dichloromethane and then solid citric acid to pH 3. The resulting mixture was extracted with 3:1 chloroform:isopropanol. The organic phase was dried over magnesium sulfate, filtered, and concentrated in vacuo. The crude product was purified by chromatography over silica gel, eluting with 2:4:0.5 ethyl acetate:toluene:acetic acid. The chromatography product was slurried in diethyl ether and filtered to give 0.31 g (69%) of a yellow solid.
