Reaction Steps
4N hydrochloric acid/ethyl acetate (15 mL) was added to a solution of the crude tert-butyl N-[8-(2,4-dimethylphenyl)-2-ethylimidazo[1,2-b]pyridazin-3-yl]carbamate in ethyl acetate (5 mL), and the mixture was stirred at room temperature for 15 hours. The mixture was neutralized by adding a 5N aqueous sodium hydroxide solution under ice-cooling, and extracted with ethyl acetate. It was washed with brine, dried over anhydrous magnesium sulfate and evaporated, to give crude 8-(2,4-dimethylphenyl)-2-ethylimidazo[1,2-b]pyridazin-3-amine.
