Sodium Hydroxide → HCID 22024327, compound

Participants

Reaction Steps

4N hydrochloric acid/ethyl acetate (30 mL) was added to a solution of the resulting tert-butyl N-[8-(2,4-dimethylphenyl)-2-ethyl-6-methylimidazo[1,2-b]pyridazin-3-yl]carbamate in ethyl acetate (10 mL), and the mixture was stirred at room temperature for 14 hours. The mixture was neutralized by adding 5N aqueous sodium hydroxide solution under ice-cooling, which was extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and evaporated, to give 8-(2,4-dimethylphenyl)-2-ethyl-6-methylimidazo[1,2-b]pyridazin-3-amine as a crude product.
