Versuchsvorschrift

To a solution of 4-chloro-1H-pyrrolo[2,3-b]pyridine-5-carboxylic acid (350 mg) in N,N-dimethylformamide (4 ml) were added N,N-carbonyl diimidazole (289 mg) and glycinemethylester hydrochloride (447 mg) successively under ambient temperature. The mixture was stirred at ambient temperature for 2 hours. To the reaction solution was added water. The precipitated solid was filtered, washed with water, and dried to obtain 4-chloro-5-(1H-imidazol-1-ylcarbonyl)-1H-pyrrolo[2,3-b]pyridine (325 mg) as a white solid.
