Reaction Steps

4-Chloro-6,7-dimethoxyquinoline (0.40 g, 1.79 mmol, p-nitroaniline (0.414 g, 2.68 mmol) and p-toluenesulfonic acid (0.154 g, 0.894 mmol) in 1-methoxy-2-propanol (5 mL) were heated to 120° C. for 8 h. The mixture was cooled to rt, triturated with ether and filtered to yield (6,7-dimethoxyquinolin-4-yl)-(4-nitrophenyl)amine (0.43 g, 73%). LCMS m/z=326 (M+1); 1H NMR (DMSO) δ: 14.37 (s, 1H), 10.72 (s, 1H), 8.54 (d, 1H, J=6.80 Hz), 8.39 (d, 2H, J=9.08 Hz), 8.05 (s, 1H), 7.74 (d, 2H, J=9.09 Hz), 7.47 (d, 1H, 8.13 Hz), 7.43 (s, 1H), 7.19 (d, 1H, J=6.85), 7.10 (d, 1H, J=7.84), 4.02 (d, 7H, J=5.48), 2.28, (s, 1H).
