Reaction Steps

In 100 mL of methanol, 240 mg (0.9 mmol) of 1-(4-nitrophenyl)-1H-imidazo[4,5-c]pyridine-4-carbonitrile was dissolved, and 170 mg of 10% palladium carbon was added thereto and the mixture solution was refluxed with stirring in a hydrogen atmosphere for one hour. The palladium carbon was removed by Celite filtration and the reaction solution was concentrated under reduced pressure, and the obtained crude product was purified by a silica gel column (dichloromethane:methanol=40:1) to obtain 65 mg (30%) of a target product as a pale yellow solid.
