Procedure

A mixture of 6-iodoimidazo[1,2-b]pyridazin-2-amine (550 mg, 2.11 mmol), tetrahydro-2H-pyran-4-carbonyl chloride (320 mg, 2.15 mmol) and N,N-dimethylacetamide (5.0 mL) was stirred at room temperature for 3 hr. The reaction mixture was poured into water, and the precipitated solid was collected by filtration, washed with water, and air-dried to give N-(6-iodoimidazo[1,2-b]pyridazin-2-yl)tetrahydro-2H-pyran-4-carboxamide as a white powder.
