6-Bromo-4-chloro-3-nitroquinoline (compound of step 1, 5.2 mmol) and 6-methoxypyridin-3-amine (commercially available, 5.2 mmol) was dissolved in acetic acid (5 mL) and the mixture was stirred overnight. Water was added and the yellow precipitate was filtered off. The precipitate was washed with water and dried. The solid obtained was partitioned and extracted with EtOAc and THF, washed with saturated aqueous NaHCO3. The organic layer was dried over anhydrous sodium sulfate and concentrated to obtain the title compound. 1H NMR (DMSO-d6, 300 MHz): 10.03 (s, 1H), 9.01 (s, 1H), 8.72 (d, J=1.5 Hz, 1H), 8.04-7.90 (m, 3H), 7.50 (dd, J=2.4, 8.7 Hz, 1H), 6.82 (d, J=9.0 Hz, 1H), 3.85 (s, 3H); MS (m/z): 377.0 (M+1)+.
