Reaction Steps
3-Aminophthalimide (2.00 g, 12.3 mmol) was dissolved in methanol (200 mL), and the solution was added with N-bromosuccinimide (2.19 g, 12.3 mmol), followed by stirring at room temperature for 50 minutes. The obtained solid was collected by filtration and washed with methanol to obtain 3-amino-6-bromophthalimide (2.21 g, yield 74%).
