Procedure

To a solution of 6-bromo-4-(5-{[4-(1-methylethyl)-1-piperazinyl]methyl}-1,3,4-oxadiazol-2-yl)-1-(phenylsulfonyl)-1H-indazole (100 mg, 0.183 mmol) in 1,4-dioxane (2.5 ml) and water (0.250 ml) was added N-[2-(methyloxy)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinyl]methanesulfonamide (78 mg, 0.238 mmol), 1,1′-bis(diphenylphosphino)ferrocene palladium dichloride (26.8 mg, 0.037 mmol) and potassium phosphate tribasic (117 mg, 0.550 mmol). The mixture was heated under microwave irradiation at 60° C. for 10 min, then the solvent was removed in vacuo and the residue partitioned between dichloromethane (5 ml) and water (5 ml), separated by hydrophobic frit and purified by silica (5 g) cartridge using a gradient of dichloromethane and methanol to give the title compound as a brown solid (122 mg).
