Benzyl Alcohol → benzyl 4-chloro-1H-pyrrolo[2,3-b]pyridine-5-carboxylate

Participants

Reaction Steps

To a suspension of 4-chloro-1H-pyrrolo[2,3-b]pyridine-5-Carboxylic acid (343 mg) in N,N-dimethylformamide (4 ml) was added phenylmethanol (375 μl) 4-dimethylaminopyridine (428 mg) and N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (676 mg). After stirring at ambient temperature for 3 days, the reaction mixture was poured into water, and extracted with EtOAc. The organic layer was washed with brine, dried over MgSO4 and evaporated in vacuo. The residue was purified by column chromatography on silica gel with chloroform to give benzyl 4-chloro-1H-pyrrolo[2,3-b]pyridine-5-carboxylate (200 mg) as a yellow powder.
