Product 1

HCID 114431811-(4-Fluorophenyl)-3-{6-[4-(2-trifluoromethylbenzoyl)piperazin-1-YL]-pyridazin-3-YL}urea

Procedure

Following the procedure of Example 5, making variations only as required to use 4-fluorophenylisocyanate in place of (2-isocyanatocyclopropyl)benzene to react with [4-(6-aminopyridazin-3-yl)piperazin-1-yl](2-trifluoromethylphenyl)-methanone, the title compound was obtained as a white solid (32.3% yield). 1H NMR (500 MHz, CDCl3) δ 12.0, 8.20, 7.53, 7.64, 7.59, 7.39, 7.33, 7.16, 6.91-6.98, 3.96-4.04, 3.83-3.90, 3.52-3.65, 3.37-3.45, 3.20-3.26. MS (ES+) m/z 489 (M+1).
