실험 절차

Into 50 ml solution of ethyl acetate containing 2.49 g of 4-(3-chloro-5-trifluoromethyl-2-pyridyloxy)benzylamine and 1.21 g of triethylamine, was dropped 2.07 g of 4-chloro-3-ethyl-1-methyl-5-pyrazolecarboxylic acid chloride synthesized in Example 2. After the completion of dropping, the mixture was stirred for 1 hour, poured into iced water and then extracted with ethyl acetate. The ethyl acetate layer was washed with an aqueous solution of sodium carbonate, water and a saturated aqueous solution of sodium chloride. After drying over anhydrous sodium sulfate, the solution was concentrated under a reduced pressure. The residue was purified on silica gel column chromatography to obtain 3.35 g of the titled compound (No. 75) shown in Table 1.
