Isonicatinamide (4.15 g) was heated in 35 ml of N,N-Dimethylformamide diethyl acetal at reflux for 3 h. The reaction mixture was cooled to ambient temperature and concentrated to give 5.02 g of N-Dimethylaminomethylene-isonicotinamide. To a solution of [4-(Quinolin-2-ylmethoxy)-phenyl]-hydrazine (3.16 g) in methanol (30 mL) and acetic acid (2.5 mL) was added N-Dimethylaminomethylene-isonicotinamide (1.10 g) and the reaction mixture heated at reflux for 72 h. The reaction mixture was concentrated onto silica gel and purified by flash chromatography to provided the title compound (514 mg). 1H NMR (400 MHz, CDCl3) δ 8.60 (d, J=5.8 Hz, 2 H), 8.22 (d, J=8.7 Hz, 1 H), 8.10 (s, 1H), 8.07 (d, J=8.7 Hz, 1H), 7.85 (d, J=7.1 Hz, 1H), 7.76 (m, 1 H), 7.66 (d, J=8.3 Hz, 1 H), 7.56 (m, 1 H), 7.56 (m, 1H), 7.38 (d, J=6.2 Hz, 2 H), 7.26 (d, J=8.7Hz, 2H), 7.11 (d, J=9.1 Hz, 2H), 5.42 (s, 2H); MS: (M+H m/z=380.3).
