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 (157 mg, 0.3 mmol) obtained in Example 117-B(i) in DME (10 mL) and water (2 mL), were added 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (93.6 mg, 0.45 mmol), [1,1-bis(diphenylphosphino)ferrocene]palladium(II)dichloride dichloromethane complex (24.5 mg, 0.03 mmol) and cesium carbonate (293 mg, 0.9 mmol) under a nitrogen atmosphere, and the mixture was stirred at 95° C. for 12 h. The reaction mixture was allowed to cool to rt, and then were added water (40 mL) and EtOAc (40 mL). The aqueous layer was extracted with EtOAc (40 mL) and then a 1:1 mixture of EtOAc and THF (60 mL×2), and the combined organic layers were dried over anhydrous magnesium sulfate. Insoluble materials were removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was washed with THF to give the title compound (64.0 mg, 41%) as a white solid.
