Reaktionsschritte

3-Iodophthalic anhydride (598 mg, 2.18 mmol) was dissolved in DMF (14 mL), and the solution was added with an aqueous solution (10 mL) of hexamethyldisilazane (HMDS) (4.6 mL, 22 mmol) and methanol (0.44 mL, 11 mmol), followed by stirring at room temperature for 18.5 hours. The reaction mixture was added with water and extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure a and the residue was purified by slurry using chloroform to obtain 3-iodophtalimide (403 mg, yield 68%).
