実験手順

Sodium hydride (60%, 0.12 g) is added to 1,2-dimethoxyethane (50 ml) and a solution of 3-(2-chloro-6-fluorophenyl)-5-(3-chloro-4-hydroxymethylphenyl) 1-methyl-1H-1,2,4-triazole (1.00 g) in 1,2-dimethoxyethane (20 ml) is added dropwise thereto at -5° C. and stirred for 20 minutes. The reaction solution is added dropwise with a solution of 2,3,5-trichloropyridine (0.60 g) in 1,2-dimethoxyethane (20 ml) at -5° C. for 10 minutes with stirring. The reaction mixture is warmed to room temperature, poured into water and extracted with ethyl acetate. 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 0.40 g of desired compound (melting point: 153.0°-155.0° C.).
