HCID 112945626-[4-(5-FLUORO-2-TRIFLUOROMETHYLBENZOYL)PIPERAZIN-1-YL]PYRIDAZINE-3-CARBOXYLIC Acid (2-CYCLOBUTYLETHYL)AMIDE

Procedure

Following the procedure of Example 3, making variations only as required to use 5-fluoro-2-(trifluoromethyl)benzoyl chloride in place of isoxazole-5-carbonyl chloride to react with 6-piperazin-1-yl-pyridazine-3-carboxylic acid (2-cyclobutylethyl)amide, the title compound was obtained as a white powder (71% yield). 1H NMR (300 MHz, CDCl3) δ 8.03, 7.83-7.71, 7.20, 7.06, 6.95, 4.01, 3.88-3.67, 3.40-3.28, 2.35, 1.89-1.57. 13C NMR (300 MHz, CDCl3) δ 166.0, 162.8, 162.6, 159.9, 145.5, 137.0, 19.7, 127.2, 125.1, 121.5, 116.9, 116.6, 115.0, 114.7, 112.6, 46.4, 44.6, 44.4, 41.3, 37.6, 36.5, 33.7, 28.3, 18.6. MS (ES+) m/z 480.5 (M+1).
