実験手順

Iodine (6.29 g, 24.8 mmol) was dissolved in ethanol (225 mL), and the solution was added with silver sulfate (3.87 g, 12.4 mmol) and 3-amino-6-bromophthalimide (3.00 g, 12.4 mmol), followed by stirring at room temperature for 23 hours. The reaction mixture was added with 10% aqueous sodium thiosulfate solution and extracted with ethyl acetate. The organic layer was washed with 0.5 mol/L hydrochloric acid and saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, the residue was purified by slurry using hexane and methanol to obtain 3-amino-4-iodo-6-bromophthalimide (4.3 g. yield 96%).
