Reaction Steps

ethyl 6-chloro-7-(4-(3,5-dichlorophenethylcarbamoyl)phenoxy)chroman-4-carboxylate (76.4 mg, 0.139 mmol) was reacted with 1.0 molar sodium hydroxide (557 μl, 0.557 mmol) in a 3:1 THF:Ethanol solution (0.05 M). After 2 hours the reaction was diluted with ethyl acetate, neutralized with 1.0 molar hydrochloric acid (585 μl, 0.585 mmol) and partitioned between saturated aqueous sodium chloride. The organic layer was dried with sodium sulfate, filtered, concentrated, and dried under high vacuum to provide the title compound (72.5 mg, 0.115 mmol, 82.8% yield) as a solid.
