Reaction Steps

The title compound was prepared in an analogous fashion to that described in Example 26 using 5-bromo-N-(4-(chlorodifluoromethoxy)phenyl)-6-(ethyl(2-hydroxyethyl)amino)nicotinamide (Stage 24.1) and 1-(tetrahydro-2H-pyran-2-yl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole to afford a yellow solid. UPLC-MS (Condition 3) tR=1.02 min, m/z=452.2 [M+H]+, m/z=450.1 [M−H]−; 1H-NMR (400 MHz, DMSO-d6) δ ppm 0.93 (t, J=7.09 Hz, 3H) 3.17-3.27 (m, 2H) 3.35-3.43 (m, 2H) 3.43-3.53 (m, 2H) 4.59 (br. s, 1H) 6.53 (d, J=1.96 Hz, 1H) 7.33 (d, J=9.05 Hz, 2H) 7.76 (br. s, 1H) 7.82-7.95 (m, 2H) 8.13 (d, J=2.45 Hz, 1H) 8.72 (d, J=2.45 Hz, 1H) 10.29 (s, 1H) 12.98 (br. s, 1H).
