Methyl 7-(4-((5-(trifluoromethyl)pyridin-2-yl)carbamoyl)phenoxy)-6-cyanochroman-4-carboxylate (9 mg, 0.018 mmol) was diluted with THF (500 μL) followed by the addition of sodium hydroxide (0.11 mL, 0.11 mmol) and methanol (100 μL). After stirring for 2 hours, the reaction was diluted with ethyl acetate and 1N HCl. The layers were separated and the organic layer was dried over MgSO4, filtered and concentrated. The material was purified using a reverse phase biotage 12iC18 column eluting with 0.1% TFA/5% ACN/95% water to 0.1% TFA/95% ACN/5% water to yield 7-(4-((5-(trifluoromethyl)pyridin-2-yl)carbamoyl)phenoxy)-6-cyanochroman-4-carboxylic acid (2.0 mg, 23% yield). MS (ESI)=484.0 (M+1).
