実験手順

To a solution of tert-butyl {3-[(2-amino[1,2,4]triazolo[1,5-a]pyridin-6-yl)oxy]-4-methylphenyl}carbamate (1.50 g, 4.22 mmol) in N,N-dimethylacetamide (5 mL) was added with stirring under ice-cooling cyclopropanecarbonyl chloride (1.15 mL, 12.7 mmol), and the mixture was stirred at room temperature for 2 hr. The reaction mixture was diluted with water and extracted with ethyl acetate. The organic layer was washed with water and saturated brine, dried over anhydrous magnesium sulfate and filtrated. The filtrate was concentrated under reduced pressure, and the residue was collected by filtration and washed with ethyl acetate-hexane to give the title compound (1.59 g, 89%) as a white solid.
