Reaction Steps

This material was prepared by reacting 7-chloro-2-{[(3R)-3-hydroxypyrrolidin-1-yl]carbonyl}thieno[3,2-b]pyridine 4a (71 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 light brown solid (76 mg, 63%). 1H NMR (DMSO-d6, 300 MHz), δ8.58 (1H, d, J=5.56 Hz), 8.32 (1H, q, J=4.38 Hz), 8.07, 8.00 (1H, s), 7.98 (1H, d, J=2.27 Hz), 7.80 (1H, d, J=8.84 Hz), 7.33 (1H, dd, J=2.27, 8.59 Hz), 6.75 (1H, d, J=5.31 Hz), 4.38, 4.33 (1H, br s), 4.01-3.93 (2H, m), 3.67-3.45 (3H, m), 3.00 (2H, t, J=7.49 Hz), 2.83 (3H, d, J=4.55 Hz), 2.06-1.80 (2H, m), 1.28 (3H, t, J=7.58 Hz).
