Participants

Reaction Steps

Following the procedure of Example 28, making variations only as required to use pyridazin-3-ylamine in place of 2-aminopyridine to react with 6-[4-(2-trifluoromethylbenzoyl)-piperazin-1-yl]pyridazine-3-carbonyl chloride, the title compound was obtained as a white powder (17.3% yield). 1H NMR (300 MHz, CDCl3) δ 10.81, 9.05, 8.70, 8.13, 7.87-7.57, 7.39, 6.95, 4.16-3.80, 3.40. C NMR (300 MHz, CDCl3) δ 167.7, 162.3, 160.1, 148.6, 144.1, 132.4, 129.6, 128.1,
