Product 1

HCID 11442719HCID 11442719, compound

Procedure

Following the procedure of Example 3, making variations only as required to use (3,3,3-trifluoro-2-methyl-2-trifluoromethylpropionyl 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 solid (35% yield). 1H NMR (300 MHz, CDCl3) δ 8.02, 7.96, 6.80, 3.91-3.75, 3.58, 1.58-1.48, 0.78-0.63, 0.48-0.43, 0.11-0.04. MS (ES+) m/z 468.2 (M+1).
