Following the Buchwald-Hartwig procedure of Example 224, tert-butyl (3S)-1-(6-(5-bromo-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridin-3-yl)pyridin-2-yl)piperidin-3-ylcarbamate and (1,1-dimethylethyl)urea were reacted 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 20 mg (23%) of 298 over three steps. ESI MS m/z 353.2 (M+1). 1H NMR (400 MHz, DMSO): 9.14 (s, 1H), 8.96 (s, 1H), 8.75 (s, 1H), 8.40 (s, 2H), 7.63 (t, J=8.0 Hz, 1H), 7.45 (d, J=7.4 Hz, 1H), 6.80 (d, J=8.5 Hz, 1H), 6.48 (s, 2H), 4.92 (d, J=11.4 Hz, 1H), 4.05 (d, J=12.9 Hz, 1H), 3.09 (m, 1H), 2.94-2.77 (m, 2H), 2.54 (s, 2H), 2.05 (d, J=9.7 Hz, 1H), 1.84 (d, J=13.1, Hz, 1H), 1.64-1.42 (m, 2H)
