A mixture of 2-methyl-3-{4-phenyl-5-[1-(tetrahydro-2H-pyran-2-yl)-1H-1,2,4-triazol-3-yl]-1,3-thiazol-2-yl}pyrazolo[1,5-a]pyridin-5-ol (100 mg, 0.22 mmol) obtained in Example 31-B(i), 5-(chloromethyl)-2-(trifluoromethyl)pyridine (64 mg, 0.33 mmol), potassium carbonate (60 mg, 0.44 mmol) and DMF (4 mL) was stirred at 60° C. for 2 h. Water (100 mL) and EtOAc (100 mL) were added to the reaction mixture, and the mixture was stirred for 30 min. The organic layer was washed with brine and dried over anhydrous magnesium sulfate. Insoluble materials were removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was dissolved in MeOH (5 mL) and THF (30 mL), 6 N hydrochloric acid (3 mL) was added, and the mixture was stirred at 70° C. for 3 h. The reaction mixture was allowed to cool to rt, and the mixture was concentrated under reduced pressure. To the residue were added EtOAc (50 mL), THF (50 mL), 8 N aqueous sodium hydroxide solution (3 mL) and water (30 mL), and the mixture was stirred for 30 min. The organic layer was washed with brine and dried over anhydrous magnesium sulfate, and insoluble materials were removed by filtration. The filtrate was concentrated under reduced pressure. The residue was crystallized from EtOAc to give the title compound (107 mg, 92%) as a white solid.
