실험 절차

A solution of N′-(6-chloropyridazin-3-yl)-2-(quinolin-6-yl)acetohydrazide (8 g crude, 25.5 mmol) in 250 mL of acetic acid was heated at 50° C. for 5 h. After the reaction was complete, the solvent was evaporated and the residue was taken up in EtOAc. The formed solid (mainly dicyclohexyl urea) was filtered off and the filtrate was evaporated to afford the title compound as yellow solid (4 g, 53%). 1H-NMR (400 MHz, MeOH-d4) δ ppm 8.82 (d, 1H), 8.33 (d, 1H), 8.25 (d, 1H), 8.0 (d, 1H), 7.93 (s, 1H), 7.83 (d, 1H), 7.53 (m, 1H), 7.42 (d, 1H), 4.79 (s, 2H). LCMS (method B): [MH]+=296.0, tR=1.876 min.
