Procedure: To a solution of N-{3-[7-(1H-pyrazol-4-yl)imidazo[1,2-b]pyridazin-3-yl]phenyl}-N′-(2,2,2-trifluoroethyl)urea (15 mg, 0.037 mmol) and 2-butenenitrile (3.8 mg, 0.056 mmol) in acetonitrile (0.5 mL) and methanol (0.2 mL) was added 1,8-diazabicyclo[5.4.0]undec-7-ene (5.6 μL, 0.037 mmol). The mixture was stirred at 60° C. overnight. The reaction mixture was stirred at 60° C. overnight. The mixture was purified by RP-HPLC (pH=10) to afford the desired product. LCMS (M+H)+: m/z=469.1. The reaction mixture was stirred at 60° C. overnight The mixture was purified by RP-HPLC (pH=10)
