N-bromobutanimide → 3-bromo-4-chloro-5-phenyl-1H-pyrrolo[2,3-b]pyridine

Participants

Reaction Steps

4-Chloro-5-phenyl-1H-pyrrolo[2,3-b]pyridine (0.912 g, 3.99 mmol) was placed in CHCl3 (5 mL) at room temperature. N-Bromosuccinimide (0.710 g, 3.99 mmol) was then added, and the reaction was stirred at room temperature for 1 hour. The reaction was diluted with DCM and washed with saturated NaHCO3. The organic fraction was dried, filtered, and concentrated to give the crude product 3-bromo-4-chloro-5-phenyl-1H-pyrrolo[2,3-b]pyridine (1.1 g, 89.7% yield).
