Procedure

6-Bromo-4-(5-{[(2R,6S)-2,6-dimethyl-4-morpholinyl]methyl}-1,3,4-oxadiazol-2-yl)-1-methyl-1H-indazole (45 mg, 0.111 mmol), N-[2-(methyloxy)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinyl]methanesulfonamide (36.4 mg, 0.111 mmol), sodium carbonate (35.2 mg, 0.332 mmol) and 1,1-bis(diphenylphosphino)ferrocene palladium dichloride (8.10 mg, 0.011 mmol) 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 by Mass Directed Automated Preparative HPLC (Method B) and the solvent was evaporated under a stream of nitrogen to give the title compound as a white solid (10 mg).
