실험 절차

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., which is stirred for 15 minutes. To the reaction solution is added dropwise a solution of 2-chloro-5-trifluoromethyl pyridine (0.60 g) in 1,2-dimethoxyethane (20 ml) at -5° C., which is stirred for 15 minutes. 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 0.80 g of desired compound (refractive index: 1.5879).
