Reaction Steps

To a solution of methyl 6-cyano-7-(4-(3-(trifluoromethyl)phenylcarbamoyl)phenoxy)chroman-4-carboxylate (0.019 g, 0.0383 mmol) in 3:1 THF/methanol (2 ml) was added 1M sodium hydroxide (0.0459 ml, 0.0459 mmol), and the reaction was stirred at ambient temperature overnight. The reaction was concentrated and partitioned between EtOAc and diluted HCl in water. The aqueous was extracted once with EtOAc, and the combined organic layers were dried over sodium sulfate, filtered and concentrated. The crude material was purified by preparative thin layer chromatography eluting with 95:5:1 dichloromethane/methanol/acetic acid to yield 10 mg of the title compound (54.2% yield). MS (apci) m/z=480.8 (M+H).
