Procedure

To a solution of 6-bromo-4-(5-{[(2R,6S)-2,6-dimethyl-4-morpholinyl]methyl}-1,3,4-oxadiazol-2-yl)-1-(phenylsulfonyl)-1H-indazole (0.82 g, 1.540 mmol) in 1,4-dioxane (15 ml) and water (1.5 ml) was added 2-(methyloxy)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinamine (0.501 g, 2.002 mmol), 1,1′-bis(diphenylphosphino)ferrocene palladium dichloride (0.225 g, 0.308 mmol) and potassium phosphate tribasic (0.981 g, 4.62 mmol). The mixture was heated at 80° C. for 2 hr, cooled and concentrated in vacuo and the residue partitioned between dichloromethane and water (20 ml), separated by hydrophobic frit and purified by silica (100 g) cartridge on Flashmaster 11, using a gradient of dichloromethane and methanol (1% triethylamine) to give the title compound as an orange solid (0.88 g).
