The title compound was prepared analogously to Step 1 in Example A(52), where iodoethane was substituted instead of methyl α-bromobutyrate and 4-Bromo-2,6-dichloro-phenol was substituted instead of 4-Bromo-2-fluorophenol of that example. 1H NMR (CDCl3) δ 0.32-0.42 (m, 2H), 0.62-0.68 (m, 2H), 1.23-1.33 (m, 1H), 3.85 (d, J=6.9 Hz, 2H), 6.82 (t, J=8.8 Hz, 1H), 7.14-7.18 (m, 1H), 7.23 (dd, J=10.5, 2.3 Hz, 1H). ESIMS (MH+): 246.1.
