実験手順

1.49 g (4.7 mmol) of 4-oxo-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-ethyl carboxylate cocrystallized with one equivalent of acetic acid is added to a suspension of 1.61 g (5.17 mmol) of diiodine and 1.31 g (5.17 mmol) of silver sulfate in anhydrous ethanol (100 mL). The reaction mixture is stirred at room temperature for 6 hours then the solvents are evaporated under vacuum. The residue is taken up in water and the product is extracted copiously with a mixture of ethyl acetate/methanol 95/5. The organic phases are dried over magnesium sulfate, filtered on celite and evaporated under vacuum to give 1.4 g (78%) of 8-iodo-4-oxo-4,5-dihydro-3H-pyrrolo[2,3-c]quinoline-1-ethyl carboxylate in the form of a white solid.
