実験手順

(2-(4-(3-Chloro-5-trifluoromethyl-2-pyridyloxy)phenoxy)propionic acid chloride hydrochloride (0.8 g) and 4-aminobenzene sulfonamide (0.5 g) were dissolved in dry tetrahydrofuran (20 ml), and the solution was stirred, with an addition of triethylamine (0.6 ml) at room temperature for 2 hours. After completion of the reaction, the solvent was evaporated under a reduced pressure, the residue was dissolved in methylene chloride and washed with 1 N hydrochloric acid, water, saturated aqueous sodium hydrogen carbonate, water and saturated aqueous sodium chloride After drying over anhydrous sodium sulfate, the residue obtained by evaporation of the solvent under a reduced pressure was purified by medium pressure column chromatography by using silica gel, to obtain the title compound (0.8 g).
