Procedure

Add 20% palladium hydroxide on carbon (11.0 g, 15 mmol) to a solution of 1-(2,4-bis-benzyloxy-3-trifluoromethyl-phenyl)-ethanone (6.00 g, 15 mmol) in ethanol (75 mL) and cyclohexene (75 mL) and stir. Purge the reaction vessel with argon. Heat to reflux. After 18 hours, cool to ambient temperature, filter and concentrate under reduced pressure to yield the title compound as a grey solid (3.00 g, 91%): 1H NMR (CD3CN) δ 2.55 (s, 3H), 6.51 (d, 1H), 7.88 (d, 1H), 13.91 (bs, 1H).
