Methyl 3-bromo-9H-pyrrolo[2,3-b:5,4-c']dipyridine-6-carboxylate → 6-(Pyrrolidinylcarbonyl)-3-bromo-9H-dipyrido[2,3-b:4',3'-d]pyrrole

Participants

Reaction Steps

3-Bromo-9H-dipyrido[2,3-b;4′,3′-d]pyrrole-6-carboxylic acid methyl ester (140 mg, 0.458 mmol) was dissolved in pyrrolidine (6 mL) and the mixture heated to reflux for 2 h. The mixture was allowed to cool and concentrated in vacuo to afford a bright orange oily solid. The residue was used without purification.
