Reaction Steps

Following the procedures as described in Example 61 and starting with tert-butyl 4-(6-(6-(1H-pyrazol-4-yl)-1H-pyrazolo[4,3-c]pyridin-1-yl)pyridin-2-yl)-1,4-diazepane-1-carboxylate and 2-bromoacetonitrile, 155 was obtained as a white solid (25 mg, 18.5%) over two steps. 1H NMR (500 MHz, CDCl3) δ (ppm) 9.064-9.065 (d, J=0.5 Hz, 1H), 8.75 (s, 1H), 8.25 (s, 1H), 8.19 (s, 1H), 8.05 (s, 1H), 7.61-7.64 (t, J=16.5 Hz, 1H), 7.28 (s, 1H), 6.43-6.45 (d, J=8.5 Hz, 1H), 5.15 (s, 2H), 3.88-3.92 (m, 4H), 3.17-3.19 (t, J=11 Hz, 2H), 2.92-2.94 (t, J=11 Hz, 2H), 2.02-2.05 (t, J=12 Hz, 2H); MS (ESI) m/z: 400 [M+H]+.
