Reaction Steps

Ethyl 6-chloro-7-(4-(2-(3,5-dichloropyridin-2-yl)ethylcarbamoyl)phenoxy)chroman-4-carboxylate (40 mg, 0.073 mmol) was diluted with THF (500 μl) followed by the addition of NaOH (364 μl, 0.36 mmol) and ethanol (300 μl). After stirring for 3 hours, the reaction was diluted with ethyl acetate and 2N HCl. The layers were separated and the organic layer was dried over MgSO4, filtered and concentrated to yield the desired compound (38 mg, 0.073 mmol, 100% yield).
