Reaction Steps

A mixture of 2-bromo-N-(1-(tert-butyldimethylsilyloxy)-2-methylpropan-2-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (210 mg, 0.5 mmol) and N,N-dimethyl-2-(6-methyl-3-(tributylstannyl)-1H-indazol-1-yl)ethanamine (1.4 g, 2.85 mmol) with tetrakis(triphenylphosphine)palladium(0) (20 mg, 0.017 mmol), copper iodide (10 mg, 0.52 mmol) in 15 mL of dry DMF was heated to 85° C. overnight under N2. The reaction mixture was cooled to room temperature, diluted with 50 mL of water, extracted with dichloromethane (8×50 mL), combined organics dried with sodium sulfate and concentrated. The crude product was used into the next step without further purification. LCMS: (M+H)+=550.
