Reaction Conditions

Reaction Steps

800 mg of N-bromosuccinimide (4 mmole) is added to a solution of 720 mg (3.7 mmoles) of 2-pyridin-4-yl-1H-pyrrolo[3,2-b]pyridine in tetrachloromethane. The brown reaction mixture is stirred 5 hours at 50° C. and concentrated. The brown residue is purified by chromatography on silica gel (ethylacetate/methanol 9/1) to give 650 mg of 3-Bromo-2-pyridin-4-yl-1H-pyrrolo[3,2-b]pyridine as white crystals.
