This material was prepared by reacting 7-chlorothieno[3,2-b]pyridine (170 mg, 1.0 mmole) with methyl 6-hydroxy-2-methylbenzo[b]thiophene-3-carboxylate 11a (267 mg, 1.2 mmole) and Cs2CO3 (488 mg, 1.5 mmole) in a manner similar to that previously described for example 1. Silica gel chromatography (10% MeOH/CHCl2) provided the title compound as a brown viscous oil (93 mg, 27%) of. 1H NMR (DMSO-d6, 300 MHz) δ 8.47 (1H, d, J=5.27 Hz), 8.41 (1H, d, J=8.85 Hz), 8.11 (1H, d, J=5.46 Hz), 7.93 (1H, d, J=2.07 Hz), 7.55 (1H, d, J=7.55 Hz), 7.32 (1H, dd, J=2.26, 8.85 Hz), 6.64 (1H, d, J=5.27 Hz), 2.77 (3H, s).
