Versuchsvorschrift

To a stirred solution of ethyl 7-(4-(2-methoxy-4-cyclopropylphenethylcarbamoyl)phenoxy)-6-chlorochroman-4-carboxylate (0.07 g; 0.133 mmol) in a mixture of 1.2 mL THF and 0.6 mL ethanol at ambient temperature was added 0.53 mL of 1M aqueous NaOH. The resulting slightly cloudy mixture was vigorously stirred at ambient temperature. After 1 hour the reaction mixture was diluted with 6 mL EtOAc and 3 mL of 1M aqueous HCl, then transferred to a separatory funnel. After shaking, the organic layer was washed with 2 mL brine, then dried over sodium sulfate and evaporated to give 62 mg of 6-chloro-7-(4-(4-cyclopropyl-2-methoxyphenethylcarbamoyl)phenoxy)chroman-4-carboxylic acid as a colorless oil. MS (apci, pos) m/z=523.
