実験手順

To 6-((3-ethyl-4-(imidazo[1,2-a]pyridine-3-carboxamido)-1H-indazol-1-yl)methyl)pyridin-2-yl trifluoromethanesulfonate (100 mg, 0.184 mmol) in IPA/THF (3 mL/1 mL) was added potassium trifluoro(vinyl)borate (36.9 mg, 0.275 mmol), 1,1′-bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex (15.0 mg, 0.0184 mmol) and triethylamine (37.2 mg, 0.367 mmol). The reaction mixture was sealed and heated to 80° C. for 16 hours. The mixture was cooled to ambient temperature and concentrated under reduce pressure. The residue was filtered through a plug of silica gel washing with EtOAc. The solution was concentrated to give the product (72 mg).
