Procedure

Ethyl 7-(4-(2-(benzo[d][1,3]dioxol-5-yl)ethylcarbamoyl)phenoxy)-6-chlorochroman-4-carboxylate (65 mg, 0.124 mmol) was dissolved in 2:1 tetrahydrofuran-ethanol and treated with 1.0 molar sodium hydroxide (496 μl, 0.496 mmol) at ambient temperature. After 3 hours, the reaction was diluted with ethyl acetate, neutralized with 1.0 molar hydrochloric acid (521 μl, 0.521 mmol), and partitioned between saturated sodium chloride aqueous solution. The organic layer was dried with sodium sulfate, filtered, concentrated, and dried under high vacuum to provide the title compound (61 mg, 0.123 mmol, 99.2% yield) as a solid.
