실험 절차

To a solution of ethyl 6-chloro-7-(4-(2-(2,4-dichlorophenyl)-2-fluoroethylcarbamoyl)phenoxy)chroman-4-carboxylate (0.161 g, 0.284 mmol) in 3:1 THF/ethanol (4 ml) was added sodium hydroxide (0.341 ml, 0.341 mmol), and the reaction was stirred for 3 days at ambient temperature. The reaction was concentrated, taken up in water, acidified with 1M hydrochloric acid, and extracted twice with EtOAc. The combined organic layers were washed with saturated sodium chloride, dried over anhydrous sodium sulfate, filtered, and concentrated to yield 121 mg of the title compound (79.7% yield).
