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-fluoropyridin-3-yl)boronic acid to afford a yellow wax. UPLC-MS (Condition 3) tR=1.06 min, m/z=481.3 [M+H]+, m/z=479.3 [M−H]−; 1H-NMR (400 MHz, DMSO-d6) δ ppm 1.70-1.80 (m, 1H) 1.80-1.91 (m, 1H) 2.89 (d, J=11.25 Hz, 1H) 3.19-3.29 (m, 2H) 3.35-3.46 (m, 1H) 4.21 (br. s, 1H) 4.86 (d, J=3.67 Hz, 1H) 7.55 (m, J=8.56 Hz, 1H) 7.61 (m, J=1.47 Hz, 1H) 7.83 (m, J=1.96 Hz, 1H) 7.98 (dd, J=13.20, 2.20 Hz, 1H) 8.07 (d, J=2.20 Hz, 1H) 8.51 (br. s, 1H) 8.60 (d, J=2.69 Hz, 1H) 8.78 (d, J=2.20 Hz, 1H) 10.30 (s, 1H).
