Versuchsvorschrift

A mixture of 3-{[4-(4-acetyl-3-hydroxy-2-propyl-phenoxymethyl)-phenyl]-hydroxy-methyl}-benzonitrile (320 mg, 0.772 mmol), potassium hydroxide (1.0 g, 17.85 mmol), water (2 mL), and ethanol (10 mL) is stirred at reflux overnight. The reaction is cooled, the pH is adjusted to 2 with aqueous 5N hydrochloric acid and diluted with water (50 mL). The product is extracted with ethyl acetate (2×50 mL). The combined extracts are washed with water (50 mL), dried over magnesium sulfate, filtered and concentrated to give the title compound (250 mg, 75%) as a white powder. 1H NMR (DMSO-d6) δ 12.85 (bs, 2H), 7.98 (s, 1H), 7.80 (d, 2H), 7.64 (d, 1H), 7.38-7.47 (m, 5H), 6.72 (d, 1H), 6.05 (d, 1H), 5.81 (d, 1H), 5.23 (s, 2H), 2.56-2.61 (m, 5H), 1.45-1.53 (m, 2H), 0.87 (t, 3H). LCMS 433 M−1.
