Reaction Steps

In 20 mL of methanol, 33 mg (0.1237 mmol) of 1-(4-nitrophenyl)-1H-imidazo[4,5-c]pyridine prepared in Step A was dissolved and the solution was stirred on 5 mg of 10% palladium carbon in a hydrogen atmosphere at room temperature at normal pressures for one hour. After removal of the palladium carbon by filtration, the solvent was distilled under reduced pressure, and the obtained product was vacuum dried to obtain 4-(imidazo[4,5-c]-pyridin-1-yl)aniline as a white solid. This product was used in process C without further purification.
