Procedure

This material was prepared by reacting 7-chloro-2-(1-methyl-1H-imidazol-2-yl)thieno[3,2-b]pyridine 1e (87 mg, 0.35 mmole) with 2-ethyl-6-hydroxybenzo[b]thiophene-3-carboxylic acid methylamide 134d (99 mg, 0.42 mmole) and Cs2CO3 (342 mg, 1.05 mmole) in a manner analogous to that described for example 1 to give a yellow solid (89 mg, 37%). 1H NMR (DMSO-d6, 300 MHz), δ8.52 (1H, d, J=5.56 Hz), 8.33 (1H, m), 7.98 (1H, d, J=2.27 Hz), 7.89 (1H, s), 7.81 (1H, d, J=8.59 Hz), 7.40 (1H, s), 7.33 (1H, dd, J=2.27, 8.84 Hz), 7.02 (1H, s), 6.97 (1H, d, J=5.31 Hz), 3.98 (3H, s), 3.00 (2H, q, J=7.58 Hz), 2.83 (3H, d, J=4.80 Hz), 1.28 (3H, t, J=7.58 Hz).
