Procedure

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 cyclopropanecarbonyl chloride (1.15 mL, 12.7 mmol) under ice-cooling, 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, and dried over anhydrous magnesium sulfate, and the insoluble material was filtered off. The filtrate was concentrated under reduced pressure, and the residue was collected by filtration and washed with ethyl acetate and hexane to give the title compound (1.59 g, 89%) as a white compound.
