Procedure

This material was prepared from 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 ethanolamine (84 μL, 1.39 mmole), N,N-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 give a yellow solid (40 mg, 28%). 1H NMR (DMSO-d6, 300 MHz) δ8.58 (1H, d, J=5.27 Hz), 8.33 (1H, t, J=5.56 Hz), 8.06 (1H, s), 7.96 (1H, d, J=2.26 Hz), 7.86 (1H, d, J=8.85 Hz), 7.32 (1H, dd, J=2.26, 8.85 Hz), 6.75 (1H, d, J=5.46 Hz), 4.76 (1H, br s), 4.13-3.81 (3H, m), 3.67-3.50 (4H, m), 3.43-3.32 (2H, m), 3.27, 3.24 (3H, s), 2.61 (3H, s), 2.18-1.94 (2H, m).
