Versuchsvorschrift

Potassium carbonate (911 mg, 6.60 mmol) was added to a solution of 2-cyclopropyl-6-fluorophenyl acetate (640 mg, 3.30 mmol) in methanol (4 ml), and the mixture was stirred at room temperature for 1 hour. After 1M hydrochloric acid was added to the reaction mixture to adjust pH to 2, this was extracted with acetic acid. The organic layer was combined and washed with a saturated aqueous NaCl solution, followed by drying with anhydrous sodium sulfate. After the solid was removed by filtration, the filtrate was concentrated to obtain 497 mg of 2-cyclopropyl-6-fluorophenol.
