A mixture of 1-acetyl-5-fluoro-4-iodo-1H-pyrrolo[2,3-b]pyridine (0.822 mmol), 1-ethyl-3-(4-nitrophenyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (1.15 mmol), tetrakis(triphenylphosphine)palladium(0) (0.041 mmol), sodium bicarbonate (2.47 mmol), water (2 mL) and N,N-dimethylformamide (6 mL) were heated to 100° C. in a sealed tube for 16 h. The reaction mixture was quenched with water (5 mL) and extracted with ethyl acetate (3×10 mL). The combined extracts were dried over sodium sulfate filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography (50% ethyl acetate/hexanes) to give the title compound as a yellow solid (80%). ESMS [M+H]+: 352.2
