Procedure

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, methoxyacetyl chloride (5.66 μL, 0.0619 mmol) and N,N-diisopropylethylamine (40.0 μL, 0.230 mmol) in DMSO (0.5 mL) was stirred at RT 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=569.2.
