6-Bromo-1-methyl-4-(5-{[4-(1-methylethyl)-1-piperazinyl]methyl}-1,3,4-oxadiazol-2-yl)-1H-indazole (45 mg, 0.107 mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indole (26.1 mg, 0.107 mmol), sodium carbonate (34.1 mg, 0.322 mmol) and 1,1-bis(diphenylphosphino)ferrocene palladium dichloride (7.85 mg, 10.73 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 passed through a 2 g silica cartridge that was then washed with methanol. The solvent was evaporated under a stream of nitrogen and the residual solid was purified firstly by silica (20 g) cartridge using a gradient of ethyl acetate and cyclohexane then by Mass Directed Automated Preparative HPLC (Method B). The solvent was evaporated under a stream of nitrogen to give the title compound as a white solid (20 mg).
