Reaction Steps

The title compound was prepared in an analogous fashion to that described in Example 169 using 5-bromo-N-(4-(chlorodifluoromethoxy)phenyl)-6-((2-hydroxyethyl)(methyl)amino)nicotinamide (Stage 179.1) and 3-fluoro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine to afford an off-white foam. HPLC (Condition 4) tR=5.51 min, UPLC-MS (Condition 3) tR=1.07 min, m/z=467.3 [M+H]+; 1H-NMR (400 MHz, DMSO-d6) δ ppm 2.69 (s, 3H) 3.39-3.61 (m, 4H) 4.65 (t, J=5.08 Hz, 1H) 7.33 (d, J=8.99 Hz, 2H) 7.77-7.94 (m, 3H) 8.11 (d, J=2.35 Hz, 1H) 8.50-8.63 (m, 2H) 8.74 (d, J=2.35 Hz, 1H) 10.21 (s, 1H).
