Reaction Steps

4-Nitropyrazole (0.5 g, 4.42 mmol) and 1-(((2R,3S)-2-(2,4-difluorophenyl)-3-methyloxiran-2-yl)methyl)-1H-1,2,4-triazol (0.93 g, 3.68 mmol) were suspended in N,N-dimethylformamide (20 mL), and anhydrous potassium carbonate (0.61 g, 4.44 mmol) was added thereto, followed by heating at 180° C. for 5 minutes by microwave irradiation while stirring. After completion of the reaction, the resulting mixture was extracted with ethyl acetate (200 mL), and the extract was washed successively with saturated ammonium chloride (200 mL) and brine (200 mL). The organic layer was dried over anhydrous magnesium sulfate and concentrated by evaporation under a reduced pressure. The resulting residue was purified by silica gel chromatography to obtain the title compound (1.0 g, yield 75%).
