Participants

Reaction Steps

Following the procedure of Example 3, making variations only as required to use 5-Fluoro-2-trifluoromethylbenzoyl chloride in place of isoxazole-5-carbonyl chloride to react with 6-piperazin-1-yl-pyridazine-3-carboxylic acid (3-cyclopropylpropyl)amide, the title compound was obtained as a white powder (28% yield). 1H NMR (400 MHz, CDCl3) δ 8.07, 7.89, 7.76, 7.28-7.24, 7.10-7.08, 7.02, 4.06-4.03, 3.90-3.86, 3.82-3.72, 3.51, 3.37, 1.76-1.70, 1.30, 0.70-0.67, 0.44-0.40, 0.03-0.003.
