Product 1

HCID 160358766-(4-(5-Fluoro-2-trifluoromethylbenzoyl)piperazin-1-yl)pyridazine-3-carboxylic acid (2-cyclopropylethyl)amide

Procedure

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 (2-cyclopropylethyl)amide, the title compound was obtained as a white powder (65% yield). 1H NMR (400 MHz, CDCl3) δ 8.05, 7.98, 7.74, 7.27-7.24, 7.09-7.06, 7.00, 4.08-3.96, 3.94-3.68, 3.55, 3.36, 1.50, 0.79-0.69, 0.48-0.42, 0.11-0.09.
