Procedure

Demethylation of nitrile (237) (0.15 g, 0.35 mmol) prepared as described in example 97 employing The procedure described in example 80, followed by trituration from methanol, gave phenol (238) (0.13 g, 89%) as an orange/yellow powder, mp 332–336° C. 1H NMR δ [(CD3)2SO] 11.10 (br s, 1H), 9.42 (br s, 1H), 8.39 (d, J=2.4 Hz, 1H), 7.96 (s, 1H), 7.69 (d, J=8.8 Hz, 1H), 7.58 (m, 1H), 7.48 (m, 3H), 7.15 (dd, J=8.8, 2.4 Hz, 1H), 4.82 (t, J=6.7 Hz, 2H), 3.02 (t, J=6.7 Hz, 2H). Found: C, 66.24; H, 3.66; N, 9.93. C23H14ClN3O3 requires: C, 66.43; H, 3.39; N, 10.10.
