실험 절차

To a 1:1 mixture (100 mg) of 7-chloro-1H-imidazo[4,5-b]pyridine and 5-chloro-1H-imidazo[4,5-b]pyridine was added N-methylcyclohexanamine (500 ul), and irradiated microwave at 200° C. for 2 hours. The reaction mixture was diluted with chloroform, washed with brine, dried over MgSO4 and evaporated. The residue was purified by flash column chromatography over NH-silica gel with a chloroform/EtOAc (100:1-100:5) as eluant to give N-cyclohexyl-N-methyl-1H-imidazo[4,5-b]pyridin-7-amine (54.8 mg) as a white solid.
