Procedure

2-{4-[3-(2-Methoxy-phenyl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-pyridin-2-yl}-N,N-dimethyl-2-oxo-acetamide was 3-(2-methoxy-phenyl)-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine (493 mg, 0.977 mmol), 2-(4-bromo-pyridin-2-yl)-2-cyano-N,N-dimethyl-acetamide (80%, 391 mg, 1.46 mmol) and 1,1′-bis(diphenylphosphino)ferrocenepalladium(II)-dichloride dichloromethane adduct (39.8 mg, 0.048 mmol) were combined in a vial under nitrogen and dissolved in acetonitrile (2.5 mL) and toluene (2.5 mL). Saturated sodium bicarbonate (5 mL) was added and the system was purged with nitrogen gas. The reaction mixture was capped and heated for 15 h at 80° C. The cooled mixture was diluted with ethyl acetate and washed with brine. The combined organic layers were dried over sodium sulfate and purified by flash chromatography on silica gel using a gradient of ethyl acetate in hexanes to afford 2-cyano-2-{4-[3-(2-methoxy-phenyl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-pyridin-2-yl}-N,N-dimethyl-acetamide.
