3-Pyridinecarboxylic acid, 4-(trifluoromethyl)- → 6-[4-(4-TRIFLUOROMETHYLPYRIDINE-3-CARBONYL)PIPERAZIN-1-YL]PYRIDAZINE-3-CARBOXYLIC Acid (3-METHYLBUTYL)AMIDE

Participants

Reaction Steps

Following the procedure of Example 9, making variations only as required to use 4-trifluoromethylpyridine-3-carboxylic acid in place of 2,5-dichlorobenzoic acid to react with 6-piperazin-1-yl-pyridazine-3-carboxylic acid (3-methylbutyl)amide, the title compound was obtained as a white powder (69% yield). 1H NMR (300 MHz, CDCl3) δ 8.87, 8.69, 8.05, 7.82, 7.62, 7.00, 4.10-3.69, 3.51-3.44, 3.38-3.35, 1.75-1.61, 1.52-1.45, 0.90. MS (ES+) m/z 451.3 (M+1).
