الإجراء التجريبي

Heat a solution of 1-(4-{4-[[3-(2-chloro-acetyl)-phenyl]-(tetrahydro-pyran-2-yloxy)-methyl]-benzyloxy}-2-hydroxy-3-methyl-phenyl)-propan-1-one (0.250 mg, 0.466 mmol) and potassium thiocyanate (90.5 mg, 0.931 mmol) in ethanol (0.20 M) overnight at 70° C. Add p-toluenesulfonic acid (10 mg) and stir overnight. Evaporate solvents and chromatograph residue. Major fraction isolated was the title compound (0.086 g, 0.179 mmol, 39%): 1H NMR (400 MHz, DMSO-d6) δ 1.09 (t, J=7.2 Hz, 3H), 2.02 (s, 3H), 3.03 (q, J=9.6 Hz, 2H), 5.10 (s, 2H), 5.20 (s, 2H), 5.82 (d, J=3.9 Hz, 1H), 6.11 (d, J=3.9 Hz, 1H), 6.70 (d, J=9.0 Hz, 1H), 7.42 (q, J=11.2 Hz, 4H), 7.51 (t, J=7.8 Hz, 1H), 7.71 (d, J=7.8 Hz, 1H), 7.81 (d, J=9.0 Hz, 1H), 7.87 (d, J=8.2 Hz, 1H), 8.04 (s, 1H), 12.88 (s, 1H). MS (m/z): 474 (M−H).
