Heat a solution of 1-(3-{[4-(4-acetyl-2-chloro-3-hydroxy-phenoxymethyl)-phenyl]-hydroxy-methyl}-phenyl)-2-chloro-ethanone (0.075 mg, 0.163 mmol) and potassium thiocyanate (159 mg, 1.63 mmol) in ethanol (0.20M) overnight at 70° C. Evaporate solvents and chromatograph residue. Major fraction isolated was the title compound (0.005 g, 0.010 mmol, 6.1%): 1H NMR (400 MHz, DMSO-d6) δ 2.61 (s, 3H), 5.10 (s, 2H), 5.30 (s, 2H), 5.82 (s, 1H), 6.11 (s, 1H), 6.88 (d, J=9.8 Hz, 1H), 7.41 (m, 4H), 7.49 (m, 1H), 7.71 (d, J=7.4 Hz, 1H), 7.87 (d, J=7.8 Hz, 1H), 7.92 (d, J=9.4 Hz, 1H), 8.04 (s, 1H), 13.12 (s, 1H). MS (m/z): 480 (M−H).
