Reaction Steps

Following the procedures as described in EXAMPLE 8 and starting with 1-(6-fluoropyridin-2-yl)-6-(5-(oxetan-3-yl)pyridin-3-yl)-1H-pyrazolo[4,3-c]pyridine and piperazine, 114 was obtained as an off-white solid (14.3 mg, 13%). 1H NMR (400 MHz, DMSO) δ 9.36-9.31 (s, 1H), 9.20-9.14 (d, J=2.1 Hz, 1H), 9.10-9.05 (s, 1H), 8.70-8.62 (m, 2H), 8.57-8.52 (t, J=2.0 Hz, 1H), 7.81-7.74 (t, J=8.1 Hz, 1H), 7.28-7.22 (d, J=7.7 Hz, 1H), 6.85-6.78 (d, J=8.4 Hz, 1H), 5.08-5.00 (dd, J=8.3, 6.1 Hz, 2H), 4.77-4.70 (t, J=6.3 Hz, 2H), 4.47-4.38 (m, 1H), 3.65-3.56 (m, 4H), 2.99-2.75 (m, 4H).; MS (ESI) m/z: 414.2 [M+H]+
