A mixture of tert-butyl 4-[6-(6-chloropyrazolo[4,3-c]pyridin-1-yl)-2-pyridyl]piperazine-1-carboxylate (0.5112 mmol; 212.1 mg), 1-ethyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrazole (1.022 mmol; 227.1 mg), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) dichloromethane adduct (0.05112 mmol; 42.6 mg), potassium acetate hydrate (0.7668 mmol; 0.77 mL) and sodium carbonate decahydrate (0.7668 mmol; 0.77 mL) in Acetonitrile (10 mL) in a pressure tube was heated under microwave at 150° C. for 15 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 tert-butyl 4-(6-(6-(1-ethyl-1H-pyrazol-4-yl)-1H-pyrazolo[4,3-c]pyridin-1-yl)pyridin-2-yl)piperazine-1-carboxylate as a dark tan solid.
