Reaction Steps

To a mixture of tert-butyl (3R)-3-{[3-bromo-5-carbamoyl-6-({4-[4-(4-methylpiperazin-1-yl)piperidin-1-yl]phenyl}amino)pyrazin-2-yl]amino}pyrrolidine-1-carboxylate (800 mg) was added 4 M hydrochloric acid (12.2 mL), followed by stirring at room temperature for 4 hours. To the reactant was added a 10% aqueous potassium carbonate solution, followed by extraction with a mixed solvent of chloroform:isopropanol (4:1). The organic phase was dried over anhydrous magnesium sulfate and filtered, and then the filtrate was concentrated to obtain 6-bromo-3-({4-[4-(4-methylpiperazin-1-yl)piperidin-1-yl]phenyl}amino)-5-[(3R)-pyrrolidin-3-ylamino]pyrazine-2-carboxamide (400 mg) as a yellow solid.
