Reaktionsschritte
2.09 g of 3-hydroxypyridine and 5.52 g of potassium carbonate were added to a dimethylformamide (20 ml) solution of 3.18 g of 3,4-difluoronitrobenzene, and the reaction liquid was stirred at 90° C. for 1 hour. The reaction liquid was diluted with ethyl acetate, washed with water and saturated saline in order, and dried with anhydrous magnesium sulfate. The solvent was evaporated away under reduced pressure, and the resulting residue was purified through silica gel column chromatography (developing solvent: hexane/ethyl acetate=9/1) to obtain the entitled compound.
