実験手順: 1-Pyrrolidine carbonylchloride (1.10 g, 9.99 mmol) was dissolved in 400 ml if dichloromethane under N2. (Tert-butoxy)-N-(4-piperidyl)carboxamide (2.0 g, 9.99 mmol) and triethyl amine (1.40 mL, 9.99 mmol) were added and the reaction mixture was stirred for three days. The reaction was quenched with sat. NaHCO3 solution and extracted with dichlorormethane. The combined organic phases were dried over MgSO4 and the solvent evaporated to give the product as a white solid. (2.63 g, 8.84 mmol, 89%). The reaction was quenched with sat. NaHCO3 solution extracted with dichlorormethane The combined organic phases were dried over MgSO4 the solvent evaporated

実験手順: This compound was prepared by using procedures analogous to those described for the synthesis of Example 85 starting from N-[3-(7-{1-[3-(cyanomethyl)azetidin-3-yl]-1H-pyrazol-4-yl}imidazo[1,2-b]pyridazin-3-yl)phenyl]-N′-(2,2,2-trifluoroethyl)urea and 1-pyrrolidinecarbonyl chloride. LCMS (M+H)+: m/z=593.2. This compound was prepared

実験手順: A mixture of N-{3-[7-(6-piperazin-1-ylpyridin-3-yl)imidazo[1,2-b]pyridazin-3-yl]phenyl}-N′-(2,2,2-trifluoroethyl)urea (20.5 mg, 0.0413 mmol) HCl salt, 1-pyrrolidinecarbonyl chloride (6.84 μL, 0.0619 mmol) and N,N-diisopropylethylamine (40.0 μL, 0.230 mmol) in DMSO (0.5 mL) was stirred at r.t. for 1 h. The mixture was diluted with DMSO, and purified by RP-HPLC (pH=10) to afford the desired product. LCMS (M+H)+: m/z=594.2. purified by RP-HPLC (pH=10)
