Reaction Conditions

Reaction Steps

In a solution of 0.45 g of 4-hydroxyiminomethyl-2-methyl-N-(2-pyridylmethyl) benzoic acid amide in 10 ml of N,N-dimethylformamide, 0.25 g of N-chlorosuccinc acid imide was added, and stirred at 70° C. for 1 hour. Then, the reaction mixture was left and cooled to room temperature, 0.41 g of 3,5-dichloro-1-(1-trifluoromethylethenyl)benzene synthesized in Step 1 of Synthetic Example 3 and 0.25 g of potassium hydrogen carbonate were added, and stirred at room temperature for 3 hours. After the completion of the reaction, the reaction mixture was poured in 50 ml of ice water, extracted with ethyl acetate (60 ml×1), the organic phase was dehydrated with saturated sodium chloride aqueous solution and dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. The residue was purified with silica gel column chromatography that was eluated with ethyl acetate-hexane (3:1), and 0.30 g of the aimed product was obtained as white crystal.
