Procedure

ethyl 6-chloro-7-(4-(4-(trifluoromethylthio)phenethylcarbamoyl)phenoxy)chroman-4-carboxylate (73.3 mg, 0.126 mmol) was reacted with 1.0 molar sodium hydroxide (506 μL, 0.506 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 (531 μL, 0.531 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 (58.7 mg, 0.106 mmol, 84.2% yield) as a solid.
