To a suspension of tert-butyl (6-iodoimidazo[1,2-b]pyridazin-2-yl)carbamate (10.2 g, 28.3 mmol) in ethyl acetate (50 mL) was added 4N hydrochloric acid/ethyl acetate (75 mL), and the mixture was stirred at room temperature for 4 hr. Diethyl ether (200 mL) was added to the reaction mixture, and the precipitate was filtrated.
