Procedure
Following the procedure of Example 15, making variations only as required to use 6-chloropyridazine-3-carboxylic acid (3-methylbutyl)amide in place of 6-chloropyridazine-3-carboxylic acid (2-cyclopropyl-2-hydroxyethyl)amide to react with piperazin-1-yl-(5-fluoro-2-trifluoromethylphenyl)methanone, the title compound was obtained as a white powder (28.3% yield). 1H NMR (400 MHz, CDCl3) δ 8.05, 7.86, 7.78-7.75, 7.28-7.22, 7.12-7.08, 7.02, 4.08-4.01, 3.91-3.86, 3.82-3.68, 3.55-3.46, 3.38, 1.73-1.65, 1.56-1.48, 0.94.
