Participants

Reaction Steps

Add zinc dust (5.00 g, 76.5 mmol) to a solution of 5-[4-(4-acetyl-3-hydroxy-2-propyl-phenoxymethyl)-benzoyl]-nicotinonitrile (4.50 g, 10.9 mmol) in acetic acid (70 ml) and stir vigorously. After 1 hour, cool reaction in an ice bath and add 1N hydrochloric acid (200 ml). Extract with ethyl acetate. Combine the organic layers, dry with sodium sulfate, filter, and concentrate under reduced pressure to give a residue. Purify the residue by flash chromatography eluting with acetone:hexanes to yield the title product as a white solid (2.80 g, 62%): 1H NMR (DMSO-d6) δ 0.86 (t, 3H), 1.47 (sextet, 2H), 2.56 (m, 5H), 5.22 (s, 2H), 5.88 (m, 1H), 6.32 (d, 1H), 6.71 (d, 1H), 7.44 (q, 4H), 7.79 (d, 1H), 8.27 (t, 1H), 8.88 (dd, 1H), 12.84 (s, 1H).
