Procedure

6-bromo-N-(6-methoxypyridin-3-yl)-3-nitroquinolin-4-amine (compound of step 2, 13.3 mmol) was hydrogenated using Raney-Ni (1 g) in THF-MeOH [(1:1), 50 mL] under 40 psi of hydrogen for 4 h at RT. After completion of the reaction, the reaction mixture was filtered through celite and washed with methanol. The filtrate was concentrated and purified (silica gel column, MeOH/CHCl3 as eluent) to obtain the title compound. 1H NMR (300 MHz, DMSO-d6): δ 8.59 (s, 1H), 7.93 (d, J=2.1 Hz, 1H), 7.78 (d, J=8.7 Hz, 3H), 7.47 (dd, J=2.1, 9.0 Hz, 2H), 6.93 (dd, J=3.0, 8.7 Hz, 1H), 6.65 (d, J=9.0 Hz, 1H), 5.42 (s, 2H), 3.85 (s, 3H); MS (m/z): 345.0 (M+1)+.
