A mixture of 6-chloro-1-(6-fluoro-2-pyridyl)pyrazolo[4,3-c]pyridine (1.759 mmol; 437.3 mg), 3-isopropenyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (2.638 mmol; 646.6 mg), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) dichloromethane adduct (0.1759 mmol; 147 mg), potassium acetate hydrate (2.638 mmol; 1.3 mL) and sodium carbonate (2.638 mmol; 1.3 mL) in Acetonitrile (10 mL) in a pressure tube was heated under microwave at 150° C. for 5 min. The mixture was cooled to room temperature. The layers were separated. The aqueous layer was extracted with EtOAc. The combined organic layer was concentrated. The residue was purified on silica eluted with 0 to 6% MeOH in DCM to afford 1-(6-fluoro-2-pyridyl)-6-(5-isopropenyl-3-pyridyl)pyrazolo[4,3-c]pyridine.
