Reaction Steps

Following the procedures as described in Example 189, 3-(6-fluoropyridin-2-yl)-5-(1-ethyl-1H-pyrazol-4-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridine and (R)-tert-butyl piperidin-3-ylcarbamate were reacted. The product was deprotected and purified to give 285 as a white solid (41.6% over two steps). 1H NMR (400 MHz, DMSO) δ 9.02 (s, 1H), 8.60 (s, 1H), 8.34 (s, 1H), 7.97 (s, 1H), 7.62 (t, J=8.0 Hz, 1H), 7.42 (d, J=7.4 Hz, 1H), 6.83 (d, J=8.5 Hz, 1H), 4.45 (d, J=8.7 Hz, 1H), 4.28-4.12 (m, 3H), 2.98 (t, J=10.9 Hz, 1H), 2.82-2.72 (m, 2H), 2.03-1.93 (m, 1H), 1.86-1.77 (m, 1H), 1.67-1.51 (m, 1H), 1.42 (t, J=7.3 Hz, 3H), 1.38-1.26 (m, 1H); 3 protons not seen.
