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. 13C NMR (300 MHz, CDCl3) δ 167.7, 162.3, 160.1, 148.6, 144.1, 132.4, 129.6, 128.1, 127.2, 126.9, 118.3, 112.1, 43.4, 44.6, 44.3, 41.3. MS (ES+) m/z 458.3 (M+1).
