Versuchsvorschrift

To a solution of pyridine-3,4-diamine (5 g) in EtOH (80 mL) was added carbon disulfide (10 mL) at room temperature. The mixture was stirred at 40° C. under a dry atmosphere (CaCl2 tube) for 10 h. The mixture was cooled to room temperature. The resulting white solid was collected by filtration and washed with ether to give 1H-imidazo[4,5-c]pyridine-2-thiol (6.1 g) as a white solid.
