Reaction Steps
To a solution of 6-iodoimidazo[1,2-b]pyridazin-2-amine hydrochloride (250 mg, 0.843 mmol) and DMAP (227 mg, 1.855 mmol) in DCM (Volume: 5.0 mL) was added methyl 4-(chlorocarbonyloxy)benzoate (199 mg, 0.927 mmol) at 25° C. The reaction was stirred at 25° C. for 1 hr to provide a dark green heterogeneous mixture which was filtered. The solid was resuspended in DCM (Volume: 5.0 mL), treated with ethanolamine (2M in MeOH, 0.843 mL, 1.686 mmol) at room temperature, and then stirred for an additional 1 hr. The reaction was then evaporated to dryness via rotary evaporation, and the resulting residue was suspended in EtOAc (Volume: 10.0 mL). The mixture was filtered, and the resulting black solid was dried under high vacuum and used without further purification.
