Participants

Reaction Steps

Following the procedure of Example 3, making variations only as required to use 2-trifluoromethylbenzoyl chloride in place of isoxazole-5-carbonyl chloride to react with 6-piperazin-1-yl-pyridazine-3-carboxylic acid (4-methylpentyl)amide, the title compound was obtained as a white solid (65.5% yield). 1H NMR (300 MHz, CDCl3) δ 8.03, 7.86, 7.74-7.72, 7.62-7.54, 7.36-7.34, 6.98, 4.08-3.98, 3.92-3.65, 3.47-3.4, 3.35-3.31, 1.62-1.53, 1.28-1.21, 0.86. 13C NMR (75 MHz, CDCl3) 6167.5, 162.9, 159.9, 145.3, 134.2, 132.3, 129.4, 127.0, 126.7, 126.2, 125.4, 121.7, 112.5, 46.3, 44.5, 44.3, 41.2, 39.6, 35.9, 27.7, 27.4, 22.4.
