Versuchsvorschrift

In a solution of 30 mg of N-acetyl-N-(5-chloro-2-pyrimidinyl)-4-hydroxyiminomethyl-2-methyl benzoic acid amide in 5 mL of 1,2-dimethoxyethane, 16 mg of N-chlorosuccinic acid imide was added and stirred at 40° C. for 30 minutes. Then the reaction mixture was left and cooled to room temperature, and 24 mg of 3,4,5-trichloro-1-(1-trifluoromethylethenyl)benzene, 10 mg of potassium hydrogen carbonate and 1 drop of water were added, and continued to stir at room temperature for 1.5 hour. After the completion of the reaction, the reaction mixture was poured in 10 mL of water, and extracted with ethyl acetate (10 mL×2). The combined organic phases were dehydrated with and dried over saturated sodium chloride aqueous solution and then 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 (gradient of 1:3 to 1:1) to obtain 11 mg of the aimed product as colorless resinous substance.
