Following the Suzuki coupling procedure of Example 159, 5-bromo-3-iodo-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridine and tert-butyl 4-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl)piperidine-1-carboxylate were reacted. The product was subsequently reacted with 3-pyridineboronic acid pinacol ester by the Suzuki coupling procedure of Example 10 and deprotected by the procedure of Example 229. The mixture was purified via reverse phase HPLC using a gradient of MeOH in water with 0.1% NH4OH to afford 25 mg (14%) of 186 over three steps. ESI MS m/z 360.1 (M+1). 1H NMR (400 MHz, DMSO) 9.44 (d, J=2.1 Hz, 1H), 9.15 (d, J=1.0 Hz, 1H), 8.64-8.54 (m, 4H), 8.17 (s, 1H), 7.53 (dd, J=8.0, 4.8 Hz, 1H), 4.08 (d, J=7.2 Hz, 2H), 2.91 (d, J=12.0 Hz, 2H), 2.41 (t, J=10.9 Hz, 2H), 1.98 (s, 1H), 1.45 (d, J=11.2 Hz, 2H), 1.18-1.05 (m, 2H)
