Participants

Reaction Steps

In 5 mL of methanol, 11 mg (0.037 mmol) of 1-(4-nitrophenyl)-1H-imidazo[4,5-c]pyridine-4-carboxylic acid methyl ester prepared in Step B was dissolved, and 100 μL of N,N-dimethylethylenediamine was added thereto and the solution was refluxed under heating with stirring for two hours. The solvent was distilled under reduced pressure, and the residue was separated by Megabond Elute Silica Gel (1 g, dichloromethane:methanol=30:1 to 4:1) to obtain 7.3 mg (51%) of 1-(4-nitrophenyl)-1H-imidazo[4,5-c]pyridine-4-carboxylic acid (2-(dimethylamino)ethyl)amide as a white solid.
