Reaction Steps

This material was prepared from 6-methoxybenzo[b]thiophene 1a (2.63 g, 16 mmole) by treatment with n-BuLi and ethyl iodide (7.80 g, 50 mmole) in a manner as previously described for example 1b to give a white solid (2.78 g, 90%). 1H NMR (DMSO-d6) δ 7.58 (1H, d, J=8.7 Hz), 7.44 (1H, d, J=2.3 Hz), 7.02 (1H, s), 6.92 (1H, dd, J=2.3, 8.7 Hz), 2.84 (2H, q, J=7.5 Hz), 1.27 (3H, t, J=7.5 Hz).
