Reaction Steps

This material was prepared by reacting 7-chloro-2-{[(3R)-3-methoxypyrrolidin-1-yl]carbonyl}thieno[3,2-b]pyridine 4b (74 mg, 0.25 mmole) with 2-ethyl-6-hydroxybenzo[b]thiophene-3-carboxylic acid methylamide 134d (71 mg, 0.30 mmole) and Cs2CO3 (244 mg, 0.75 mmole) in a manner analogous to that described for example 1 to give a yellow solid (34 mg, 19%). 1H NMR (DMSO-d6, 300 MHz), δ8.59 (1H, d, J=5.31 Hz), 8.33 (1H, q, J=4.46 Hz), 8.06 (1H, s), 7.99 (1H, d, J=2.27 Hz), 7.81 (1H, d, J=8.84 Hz), 7.34 (1H, dd, J=2.27, 8.84 Hz), 6.76 (1H, d, J=5.56 Hz), 4.08-3.83 (3H, m), 3.67-3.48 (2H, m), 3.27, 3.24 (3H, s), 3.00 (2H, t, J=7.49 Hz), 2.83 (3H, d, J=4.55 Hz), 2.16-1.95 (2H, m), 1.28 (3H, t, J=7.58 Hz).
