実験手順
This material was prepared by treatment of 2-ethyl-6-hydroxybenzo[b]thiophene 134b (1.60 g, 9 mmole) with acetyl chloride (1 ml, 1.10 g, 14 mmole) and Et3N (2 ml, 1.45 g, 14 mmole) in a manner as previously described for example 8b to give a white solid (2.93 g, 93%). 1H NMR (DMSO-d6) δ7.72 (1H, d, J=8.5 Hz), 7.68 (1H, d, J=2.2 Hz), 7.15 (1H, s), 7.08 (1H, dd, J=2.2, 8.5 Hz), 2.89 (2H, q, J=7.5 Hz), 2.28 (3H, s), 1.29 (3H, t, J=7.5 Hz).
