Procedure
Following the procedure of Example 14, making variations only as required to use 3,3,3-trifluoro-2-hydroxy-2-methylpropionic acid in place of 4,4,4-trifluoro-2-methylbutyric acid to react with 6-piperazin-1-yl-pyridazine-3-carboxylic acid (3-methylbutyl)amide, the title compound was obtained as a white solid (55% yield). m.p. 181-183° C. 1H NMR (300 MHz, CDCl3) δ 8.07, 7.98, 7.01, 4.86, 3.92-3.81, 3.55, 1.74, 1.51, 0.81-0.68, 0.46, 0.09. 13C NMR (75 MHz, CDCl3) δ 167.2, 163.1, 160.0, 145.4, 127.1, 126.3, 122.5, 112.5. 76.8-75.6 (q, J=117 Hz, C-19F), 44.6, 39.7, 35.3, 20.5, 8.5, 4.8. MS (ES+) m/z 416 (M+1).
