실험 절차

To a solution of 0.5 g of 4-(3-(3,5-dichlorophenyl)-4,4,4-trifluoro-2-butenoyl)benzoic acid that was synthesized under Synthetic Example 4 and 0.21 g of 2-picolylamine in 6 mL of N,N-dimethylformamide, 0.32 g of 1-(3-(diethylamino)propyl)-3-ethylcarbodiimide chloride was added at room temperature and the mixture was stirred for 72 hours. After the completion of reaction, 20 mL of ethyl acetate and 15 mL of saturated saline were added to the reaction solution, the mixture was separated to extract an aqueous layer with 10 mL of ethyl acetate whereto an organic layer was added, the resulting mixture was washed with 10 mL of water and dried with anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure. After purification of the resulting residue using silica gel column chromatography that was eluted with ethyl acetate-hexane (5:1) to obtain 0.17 g of aimed product as resinous matter.
