Reaction Steps

Following the procedures of Example 143, 3-(6-fluoropyridin-2-yl)-5-(pyridin-3-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridine and piperazine were reacted and purified via reverse phase HPLC using a gradient of MeOH in water with 0.1% NH4OH to afford 42 mg (78%) of 162. ESI MS m/z 358.1 (M+1). 1H NMR (400 MHz, DMSO): 9.24 (d, J=8.1 Hz, 1H), 8.90 (s, 1H), 8.61 (s, 1H), 8.42 (d, J=7.2 Hz, 1H), 7.74 (d, J=7.9 Hz, 1H), 7.56 (d, J=6.7 Hz, 1H), 6.96 (d, J=8.1 Hz, 1H), 3.82 (s, 2H), 3.17 (s, 2H)
