N-bromobutanimide → HCID 23152327, compound

Participants

Reaction Steps

To a solution of ethyl 3-cyclohexyl-1-ethoxycarbonylmethyl-1H-pyrrolo[2,3-b]pyridine-6-carboxylate (463 mg, 1.34 mmol) in carbon tetrachloride (10 ml) was added N-bromosuccinimide (287 mg, 1.61 mmol), and the mixture was heated under reflux for 4 hr. The mixture was allowed to cool to room temperature and the solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography (hexane:ethyl acetate-5:1) to give ethyl 2-bromo-3-cyclohexyl-1-ethoxycarbonylmethyl-1H-pyrrolo[2,3-b]pyridine-6-carboxylate (457 mg, yield 64%).
