Product 1

HCID 113172376-[4-(4,4,4-TRIFLUORO-3-TRIFLUOROMETHYLBUT-2-ENOYL)PIPERAZIN-1-YL]PYRIDAZINE-3-CARBOXYLIC Acid (2-CYCLOPROPYLETHYL)AMIDE

Procedure

Following the procedure of Example 9, making variations only as required to use 4,4,4-trifluoro-3-trifluoromethylbut-2-enoic acid in place of 2,5-dichlorobenzoic acid to react with 6-piperazin-1-yl-pyridazine-3-carboxylic acid (2-cyclopropylethyl)amide, the title compound was obtained as a white powder (45.4% yield). 1H NMR (CDCl3) δ 8.07, 7.97, 7.10, 7.01, 3.87-3.74, 3.58-3.50, 1.54-1.47, 0.78-0.68, 0.48-0.42, 0.10-0.05.
