Procedure

Ethyl 6-chloro-7-(4-(3-phenoxyphenethylcarbamoyl) phenoxy)chroman-4-carboxylate (71.6 mg, 0.125 mmol) was reacted with 1.0 molar sodium hydroxide (501 μl, 0.501 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 (526 μl, 0.526 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 (56.4 mg, 0.104 mmol, 82.8% yield) as a solid.
