Versuchsvorschrift
Following the procedure of Example 15, making variations only as required to use 2-[(6-chloropyridazine-3-carbonyl)amino]-4-methylpentanoic acid methyl ester 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 solid (36% yield). 1H NMR (400 MHz, CDCl3) δ 8.16, 8.04, 7.85, 7.66-7.53, 7.28, 7.00, 4.82-4.77, 4.14-3.68, 3.58-3.51, 1.83-1.60, 1.03-0.95.
