Reaction Conditions

Reaction Steps

In dimethylformamide (40 mL), 2-ethyl-5-hydroxyiminomethylnitrobenzene (4.30 g) and N-chlorosuccinimide (2.97 g) were dissolved, and the mixture was stirred at 60° C. for 1 hour. The reaction mixture was cooled to room temperature, and thereto was added 2-(3,5-dichlorophenyl)-3,3,3-trifluoro-1-propene (3.5 g), followed by triethylamine (1.7 g), and then the mixture was stirred for 6 hours. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The resulting residue was subjected to silica gel column chromatography to obtain 5-[5-(3,5-dichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazol-3-yl]-2-ethylnitrobenzene (5.74 g).
