Versuchsvorschrift

Following the procedure of Example 3, making variations only as required to use 2,5-difluorobenzoyl 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 powder (53% yield). 1H NMR (400 MHz, CDCl3) δ 8.08, 8.0, 7.17-7.11, 7.03, 4.02-3.92, 3.85-3.83, 3.59-3.5, 1.52, 0.74-0.69, 0.46-0.40, 0.09-0.04.
