Crude 3-fluoro-5-iodo-N,N-dimethyl-2-[(pyridin-4-ylmethyl)-amino]-benzamide (˜1.63 mmol) from the previous step and 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 (822 mg, 1.63), [1,1′-bis(diphenylphosphino)-ferrocene]dichloropalladium(II) complex with dichloromethane (1:1, 133 mg, 0.16 mmol), acetonitrile (8 ml) and 2 M aqueous sodium carbonate solution (4 ml) were placed in a microwave reactor and irradiated to 100° C. for 10 minutes. The reaction mixture was concentrated in vacuo and the residue partitioned between dichloromethane and water. The organic layer was dried over sodium sulfate, and concentrated. The crude product was purified by flash chromatography on silica gel (0 to 100% [10% methanol in ethyl acetate] in hexanes) to afford 236 mg (22% for 2 steps) of 3-fluoro-5-[3-(2-methoxy-phenyl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-N,N-dimethyl-2-[(pyridin-4-ylmethyl)-amino]-benzamide. MS: m/z 650.3 (M+H+).
