実験手順

A mixture of N-(6-hydroxy[1,2,4]triazolo[1,5-a]pyridin-2-yl)cyclopropanecarboxamide (200 mg, 0.917 mmol), 1,3-difluoro-5-nitrobenzene (437 mg, 2.75 mmol), potassium carbonate (380 mg, 2.75 mmol) and N,N-dimethylformamide (6 mL) was stirred at 140° C. for 6 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 yellow solid.
