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-(2-trifluoromethylphenyl)methanone, the title compound was obtained as a white powder (63.2% yield). 1H NMR (500 MHz, CDCl3) δ 8.05, 7.98, 7.75, 7.64, 7.57, 7.37, 7.00, 4.06, 3.89, 3.82-3.64, 3.49, 3.36, 1.70, 1.50, 0.95.
