Reaction Steps

The title compound was prepared in an analogous fashion to that described in Example 151 using (R)-5-bromo-N-(3-fluoro-4-(trifluoromethoxy)phenyl)-6-(3-hydroxypyrrolidin-1-yl)nicotinamide (Stage 198.1) 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=488.3 [M+H]+, m/z=486.3 [M−H]−; 1H-NMR (400 MHz, DMSO-d6) δ ppm 1.75 (s, 1H) 1.81-1.92 (m, 1H) 2.87 (d, J=11.25 Hz, 1H) 3.15-3.27 (m, 2H) 3.33-3.44 (m, 1H) 4.21 (br. s, 1H) 4.87 (d, J=3.42 Hz, 1H) 7.51-7.64 (m, 2H) 7.98 (dd, J=13.20, 2.20 Hz, 1H) 8.08 (d, J=2.20 Hz, 1H) 8.40 (t, J=1.96 Hz, 1H) 8.79 (d, J=2.20 Hz, 1H) 8.90 (d, J=1.96 Hz, 1H) 9.03 (d, J=1.96 Hz, 1H) 10.31 (s, 1H).
