To a solution of 4-chloro-5-(1H-imidazol-1-ylcarbonyl)-1H-pyrrolo[2,3-b]pyridine(300 mg) in N,N-dimethylformamide (3 ml) were added N-ethyl-N-isopropylpropane-2-amine (0.64 ml) and glycine methylester hydrochloride (305 mg) at ambient temperature. The mixture was warmed immediately to 60° C. and stirred at 60° C. for 2 hours. After to the reaction solution was added water, the mixture was stirred for 1 hour. The precipitated solid was filtered, washed with water, and dried to obtain methyl N-[(4-chloro-1H-pyrrolo[2,3-b]pyridin-5-yl)carbonyl]glycinate (267 mg) as a white solid.
