6-Chloro-7-(4-(2-(2-cyclopropyl-6-(trifluoromethyl)pyridin-3-yl)ethylcarbamoyl)phenoxy)chroman-4-carboxylic acid (15 mg, 0.027 mmol) was diluted with methanol (1 mL) followed by the addition of NaOMe in methanol (53 μL, 0.027 mmol). After stirring for 2 hours, the reaction was concentrated and dried under high vacuum pressure for 2 hours. The material was diluted with hexanes, sonicated and concentrated to afford 6-chloro-7-(4-(2-(2-cyclopropyl-6-(trifluoromethyl)pyridin-3-yl)ethylcarbamoyl)phenoxy)chroman-4-carboxylic acid sodium salt (15 mg, 0.027 mmol, 100% yield) as a white solid.
