Reaction Steps

This material was prepared by the reaction of 6-[(2-{[(3R)-3-methoxypyrrolidin-1-yl]carbonyl}thieno[3,2-b]pyridin-7-yl)oxy]-2-methylbenzo[b]thiophene-3-carboxylic acid 123b (130 mg, 0.278 mmole) with (aminomethyl)cyclopropane (120 μL, 1.39 mmole), diisopropylethylamine (0.15 mL, 0.83 mmole), and HBTU (263 mg, 0.694 mmole) in a manner similar to that previously described for example 117 to afford a pale yellow solid (42 mg, 24%). 1H NMR (DMSO-d6, 300 MHz) δ 8.61 (1H, d, J=5.56 Hz), 8.49 (1H, t, J=5.56 Hz), 8.06 (1H, s), 7.97 (1H, s), 7.84 (1H, d, J=8.59 Hz), 7.34 (1H, dd, J=2.27, 8.84 Hz), 6.79 (1H, d, J=5.56 Hz), 4.11–3.80 (3H, m), 3.70–3.46 (2H, m), 3.27, 3.24 (3H, s), 3.20 (2H, t, J=6.19 Hz), 2.62 (3H, s)2.18–1.91 (2H, m), 1.08 (1H, m), 0.47 (2H, m), 0.26 (2H, m).
