Cyclopropanemethanamine → 2-Methyl-6-{[2-(1-methyl-1H-imidazol-2-yl)thieno[3,2-b]pyridin-7-yl]oxy}benzo[b]thiophene-3-carboxylic acid (cyclopropylmethyl)amide

Participants

Reaction Steps

This material was prepared from the reaction of 2-methyl-6-{[2-(1-methyl-1H-imidazol-2-yl)thieno[3,2-b]pyridin-7-yl]oxy}benzo[b]thiophene-3-carboxylic acid 117b (70 mg, 0.166 mmole), (aminomethyl)cyclopropane (43 μL, 0.50 mmole) and diisopropylethylamine (58 μL, 0.33 mmole), and HBTU (94 mg, 0.25 mmole) in a manner similar to that previously described for example 117 to afford a pale yellow solid (64 mg, 53%). 1H NMR (DMSO-d6, 300 MHz) δ8.61 (1H, d, J=5.46 Hz), 8.49 (1H, t, J=5.65 Hz), 8.07 (1H, s), 7.99 (1H, d, J=2.26 Hz), 7.85 (1H, d, J=8.67 Hz), 7.63 (1H, s), 7.37 (1H, s), 7.36 (1H, dd, J=2.4, 8.67 Hz), 6.81 (1H, d, J=5.65 Hz), 4.01 (3H, s), 3.20 (2H, t, J=6.31 Hz), 2.62 (3H, s), 1.08 (1H, m), 0.47 (2H, m), 0.27 (2H, m).
