Procedure

To a solution of 3-(1-cyano-1-methylethyl)benzoyl chloride synthesized above in N,N-dimethylacetamide (2.0 mL) was added N-[6-(5-amino-2-methylphenoxy)[1,2,4]triazolo[1,5-a]pyridin-2-yl]cyclopropanecarboxamide (75 mg, 0.233 mmol), and the mixture was stirred at room temperature for 10 hr. The reaction mixture was diluted with ethyl acetate (100 mL), washed with 5% aqueous sodium hydrogen carbonate solution (50 mL) and saturated brine (50 mL), and dried over anhydrous sodium sulfate. The insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by basic silica gel column chromatography (hexane/ethyl acetate=50/50→0/100), and the obtained oil was triturated with ethyl acetate and diisopropyl ether to give the title compound (40.8 mg, 35%) as a colorless powder.
