Procedure

Add lithium hydroxide (289 mg, 12.06 mmol) to a solution of 5-[4-(4-acetyl-3-hydroxy-2-propyl-phenoxymethyl)-benzoyl]-nicotinonitrile (500 mg, 1.21 mmol) in dioxane (10 mL) and water (10 mL) and stir. Heat solution to reflux. After 1 hour cool to ambient temperature, add water (100 mL) and wash with ethyl acetate. Acidify with 10% aqueous hydrochloric acid (15 mL), and extract with ethyl acetate. Combine organic layers, dry with sodium sulfate, filter and concentrate under reduced pressure to give a residue. Purify residue by sonicating in ether for 1 hour. Filter the resulting precipitate to yield the title compound as a beige solid (262 mg, 50%): 1H NMR (DMSO-d6) δ 0.86 (t, 3H), 1.48 (sextet, 2H), 2.54 (s, 3H), 2.59 (t, 2H), 5.38 (s, 2H), 6.70 (d, 1H), 7.62 (d, 2H), 7.79 (d, 1H), 7.84 (d, 2H), 8.42 (s, 1H), 9.05 (s, 1H), 9.24 (s, 1H), 12.82 (s, 1H), 13.72 (bs, 1H); MS (esi negative) m/z (rel intensity) 432 (100).
