Ethyl 6-chloro-7-(4-(2-(2-cyclopropyl-6-(trifluoromethyl)pyridin-3-yl)ethylcarbamoyl)phenoxy)chroman-4-carboxylate (15 mg, 0.025 mmol) was diluted with THF (200 μL) followed by the addition of aq. 1N NaOH (127 μL, 0.13 mmol) and ethanol (100 μL). After stirring for 2 hours, the reaction was diluted with ethyl acetate and 2N aqueous HCl. The layers were separated and the organic layer was dried over MgSO4, filtered and concentrated to yield 6-chloro-7-(4-(2-(2-cyclopropyl-6-(trifluoromethyl)pyridin-3-yl)ethylcarbamoyl)phenoxy)chroman-4-carboxylic acid (14 mg, 0.025 mmol, 98% yield).
