A mixture of 5-bromo-6-chloro-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 44.2, 250 mg, 0.632 mmol) and K2CO3 (131 mg, 0.948 mmol) in 2-methoxyethanol (997 μl, 12.64 mmol) was stirred at 110° C. for 4 h. The solvent was evaporated off under reduced pressure to afford the title compound which was used directly. UPLC-MS (Condition 2) tR=1.18 min, m/z=435.2/437.2 [M+H]+; 1H-NMR (600 MHz, DMSO-d6) δ ppm 3.32 (s, 3H) 3.64-3.76 (m, 2H) 4.48-4.59 (m, 2H) 7.38 (d, J=8.66 Hz, 2H) 7.85 (d, J=9.03 Hz, 2H) 8.55 (d, J=2.07 Hz, 1H) 8.72 (d, J=2.07 Hz, 1H) 10.47 (s, 1H).
