Water → N-(6-iodoimidazo[1,2-b]pyridazin-2-yl)cyclopropanecarboxamide

Participants

Reaction Steps

To a solution (10 mL) of 6-iodoimidazo[1,2-b]pyridazin-2-amine (1.0 g, 3.85 mmol) in N,N-dimethylacetamide was added cyclopropylcarbonyl chloride (0.38 mL, 4.23 mmol), and the mixture was stirred at room temperature for 4 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate/tetrahydrofuran. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and filtrated. The solvent was evaporated under reduced pressure, and the residue was washed with hexane/ethyl acetate (4/1) to give the title compound (1.01 g, 80%) as a dark brown powder.
