To a 25 mL microwave reactor vial was charged 3-{1-[(2,5-difluorophenyl)acetyl]-2,3-dihydro-1H-indol-5-yl}-7-iodothieno[3,2-c]pyridin-4-amine (150 mg, 0.274 mmol), 1H-pyrazol-3-ylboronic acid (30.7 mg, 0.274 mmol), 1,1′-bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex (11.19 mg, 0.014 mmol), and sodium carbonate (58.1 mg, 0.548 mmol) followed by dioxane (5 mL), and water (1 mL). The reaction was heated at 120° C. for 30 min in microwave reactor. Ethyl acetate (20 mL) was added and the layers were separated. The organic layer was washed with brine, concentrated, and the residue purified by silica gel chromatography (0%-100% EtOAc in hexanes). Product came out at 100% EtOAc in 5 minutes, the fractions with the product were combined and evaporated to dryness to afford the title compound as a light gray solid (48 mg).
