Ethyl Acetate → 5-Bromo-3-iodo-1H-pyrrolo(2,3-b)pyridine

Participants

Reaction Steps

5-Bromo-1H-pyrrolo[2,3-b]pyridine (5 g, 25 mmol) was dissolved in anhydrous acetone (75 ml) and added N-iodo succinimide (6.18 g, 27.5 mmol) under nitrogen atmosphere and stirred at RT for 2 h. The reaction was monitored by TLC (10% Ethyl acetate in hexane). The reaction mixture was cooled to RT and filtered, washed with cold acetone (50 ml) and dried under vacuum to afford 7.05 g (87% yield) of 5-bromo-3-iodo-1H-pyrrolo[2,3-b]pyridine.
