실험 절차

A mixture of tert-butyl 4-[6-(6-chloropyrazolo[4,3-c]pyridin-1-yl)pyrazin-2-yl]-1,4-diazepane-1-carboxylate (0.2526 mmol; 108.6 mg), 2-fluoro-5-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (0.3789 mmol; 89.84 mg), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) dichloromethane adduct (0.02526 mmol; 21.1 mg), potassium acetate (0.3789 mmol; 0.38 mL) and sodium carbonate (0.3789 mmol; 0.38 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 layers were concentrated. The residue was purified on silica eluted with 0 to 5% MeOH in DCM with 1% NH4OH to afford tert-butyl 4-[6-[6-(2-fluoro-5-methyl-3-pyridyl)pyrazolo[4,3-c]pyridin-1-yl]pyrazin-2-yl]-1,4-diazepane-1-carboxylate (106.6 mg, 84%).
