実験手順
Demethylation of alcohol (225) (96 mg, 0.22 mmol) prepared as described in example 290 employing the procedure described in example 80 was followed by chromatography on silica eluting with ethyl acetate/hexane (4:1). Crystallisation from ethyl acetate/hexane gave phenol (226) (28 mg, 31%) as an orange/yellow powder, mp 290–295° C. 1H NMR δ [(CD3)2SO] 11.04 (br s, 1H), 9.30 (s, 1H), 8.40 (d, J=2.4 Hz, 1H), 7.79 (s, 1H), 7.63 (m, 2H), 7.55 (d, J=8.8 Hz, 1H), 7.47 (m, 3H), 7.11 (dd, J=8.8, 2.4 Hz, 1H), 5.00 (d, J=5.4 Hz, 1H), 4.86 (t, J=5.4 Hz, 1H), 4.51 (dd, J=3.8, 14.9 Hz, 1H), 4.35 (dd, J=7.5, 14.9 Hz, 1H), 3.89 (m, 1H), 3.41 (m, 2H).
