Procedure

To 30 ml of N,N-dimethylformamide are added 2-chloro-4-trifluoromethyl phenol (0.29 g) and potassium carbonate (0.25 g) and 5-(4-bromomethyl-3-chlorophenyl) 3-(2-chloro-6-fluorophenyl)-1-methyl-1H-1,2,4-triazole (0.60 g) is added thereto at room temperature with stirring, which is stirred at 120° C. for 1 hour. On completion of the reaction, the reaction solution is cooled to room temperature, poured into water and extracted with toluene. The organic layer is washed with water, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The concentrate is purified by silica gel column chromatography to give 0.61 g of desired compound (melting point: 113.0°-114.0° C.).
