The title compound was prepared in an analogous fashion to that described in Example 151 using 5-bromo-N-(4-(chlorodifluoromethoxy)phenyl)-6-((2-hydroxyethyl)(methyl)amino)nicotinamide (Stage 179.1) and 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)nicotinonitrile to afford a yellow solid. UPLC-MS (Condition 3) tR=1.05 min, m/z=474.3 [M+H]+, m/z=472.3 [M−H]−; 1H-NMR (400 MHz, DMSO-d6) δ ppm 2.70 (s, 3H) 3.48 (d, J=5.38 Hz, 2H) 3.56 (d, J=5.38 Hz, 2H) 4.66 (br. s, 1H) 7.36 (d, J=9.05 Hz, 2H) 7.81-7.93 (m, 2H) 8.15 (d, J=2.45 Hz, 1H) 8.46 (t, J=2.08 Hz, 1H) 8.77 (d, J=2.20 Hz, 1H) 9.01 (dd, J=7.21, 2.08 Hz, 2H) 10.23 (s, 1H).
