A mixture of 2-(3-(5-(chloromethyl)-1,2,4-oxadiazol-3-yl)phenyl)imidazo[1,2-b]pyridazine(1.5 mmol), sodium iodide(cat.) and 2-methoxyethanamine(3 mmol) in 25 mL EtOH was stirred under reflux for 2 h. The mixture was concentrated in vacuo and the crude product was purified by column chromatography on silica gel to give the N-((3-(3-(imidazo[1,2-b]pyridazin-2-yl)phenyl)-1,2,4-oxadiazol-5-yl)methyl)-2-methoxyethanamine.
