実験手順

6-Bromo-1-methyl-4-(5-{[4-(1-methylethyl)-1-piperazinyl]methyl}-1,3,4-oxadiazol-2-yl)-1H-indazole (40 mg, 0.095 mmol), N-[2-(methyloxy)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinyl]methanesulfonamide (31.3 mg, 0.095 mmol), sodium carbonate (30.3 mg, 0.286 mmol) and 1,1-bis(diphenylphosphino)ferrocene palladium dichloride (6.98 mg, 9.54 μmol) were added to a microwave vial and dissolved in 1,4-dioxane (0.5 ml) and water (0.5 ml). The reaction mixture was heated under microwave irradiation at 110° C. for 15 mins. The reaction mixture was evaporated under a stream of nitrogen and the residual solid was dissolved in DMSO (1 ml), filtered through a frit and purified by Mass Directed Automated Preparative HPLC (Method B). The solvent was evaporated under a stream of nitrogen and the residue was dissolved in 1,4-dioxane (1 ml) and water (1 ml), frozen in a cardice bath and placed on the freeze-drier for 18 h to afford the title compound as a white solid (20 mg).
