실험 절차

With cooling with ice, 4.4 ml of triethylamine and 2.8 g of picolinic acid chloride hydrochloride were added to a chloroform (30 ml) solution of 2.65 g of methyl 2-amino-5-[4-(ethylsulfonyl)phenoxy]benzoate, and stirred at room temperature for 90 minutes. Aqueous saturated sodium hydrogencarbonate solution was added to the reaction liquid, extracted with chloroform, and the organic layer was washed with saturated saline water. After dried, the solvent was evaporated away under reduced pressure, and the residue was purified through silica gel column chromatography (developing solvent: hexane/ethyl acetate=2/1 to 1/1) to obtain 1.9 g of the entitled compound as a creamy white solid.
