To a stirred suspension of 4-bromo-3-iodo-1-isopropyl-1H-pyrrolo[2,3-b]pyridine (D10) (1.500 g, 4.11 mmol), 5-fluoro-1-methyl-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)indoline (1.367 g, 4.93 mmol), bis(triphenylphosphine)palladium(II) chloride (0.288 g, 0.411 mmol), 2M sodium carbonate aq. solution. (20.55 mL, 41.1 mmol) in ACN (10 mL), DMF (10 mL) and DCM (5 mL) at RT was degassed under nitrogen for 10 mins. The reaction mixture was heated to 60° C. under nitrogen atmosphere for an hour. The reaction mixture was cooled to RT and partitioned between ethyl acetate/water (ca. 50 mL each). The aqeuous layer was separated and extracted with ethyl acetate (ca. 30 mL twice). The combined organic layer was dried over MgSO4 and solvent removed in vacuo. The residue was purified using silica chromatography (eluted with 0-20% ethyl acetate/cyclohexane) to afford the title compound (910 mg). LCMS (A): m/z (M+H)+ 388/390, C19H19BrFN3 requires 387/389 (acidic).
