Procedure

To a suspension 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, 0.218 mmol) obtained in Example 31-B-(i) and potassium carbonate (60.3 mg, 0.436 mmol) in DMF (4 mL), was added 4-(3-chloropropyl)morpholine (71.3 mg, 0.436 mmol) obtained above and the mixture was stirred for 5 h at 60° C. To the reaction mixture, were added EtOAc (20 mL) and saturated aqueous solution of sodium bicarbonate (15 mL). The organic layer was separated and then aqueous layer was extracted with EtOAc (5 mL). The combined organic layers were washed with brine (5 mL) and then dried over anhydrous sodium sulfate. Insoluble materials were removed by filtration and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (EtOAc/hexane=30/70→60/40) to give the title compound (128 mg, quant) as a colorless solid
