Participants

Reaction Steps

Following the procedures as described in Example 189, 3-(6-fluoropyridin-2-yl)-5-(1-methyl-1H-pyrazol-4-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridine and tert-butyl 1-piperazinecarboxylate were reacted. The product was deprotected to give 234 as a white solid (61% over two steps). 1H NMR (400 MHz, DMSO) δ 9.03 (s, 1H), 8.53 (s, 1H), 8.11 (s, 1H), 7.82 (s, 1H), 7.65 (t, J=7.9 Hz, 1H), 7.45 (d, J=7.2 Hz, 1H), 6.83 (d, J=8.5 Hz, 1H), 3.91 (s, 3H), 3.63 (s, 4H), 2.94 (s, 4H); two protons not seen. LC/MS: m/z 361.1 [M+1]
