Versuchsvorschrift
To a stirred solution of 3-[3-(4-fluorophenoxy)phenyl]-2-cyclopentenone (10 g; 0.0373M) in ethanol-pyridine (75 ml-21 ml) was added hydroxylamine hydrochloride (3.37 g; 0.0485M) at room temperature. After stirring for 4 hrs, solvent was removed. To the residue was added dilute aqueous HCl (100 ml), and the whole was extracted with ethyl acetate (200 ml×1, 100 ml×1). The combined organic layers were washed with water (100 ml), brine (100 ml), dried over MgSO4, and concentrated in vacuo to give 12 g of crude subtitle compound [E] as a brown oil, which was used without further purification.
