Procedure

To a suspension of 6-bromo-2-methyl-3-{4-phenyl-5-[1-(tetrahydro-2H-pyran-2-yl)-1H-1,2,4-triazol-3-yl]-1,3-thiazol-2-yl}imidazo[1,2-a]pyridine (1.04 g, 2.0 mmol) obtained by similar manner with Example 117-B(i) in DME (70 mL) and water (14 mL), were added potassiumvinyltrifluoroborate (410 mg, 3.0 mmol), [1,1-bis(diphenylphosphino)ferrocene]palladium(II) dichloride dichloromethane complex (170 mg, 0.2 mmol) and cesium carbonate (1.90 g, 6.0 mmol) under a nitrogen atmosphere, and the mixture was stirred at 95° C. for 4 h. The reaction mixture was allowed to cool to rt, and then was added EtOAc (40 mL). The resulting precipitate was collected by filtration and washed with water and diethyl ether to give the title compound (890 mg, 95%) as a gray solid.
