Reaction Steps

14.8 g. (100 mMole) 5,6-diaminobenzimidazole, 10.7 g. (100 mMole) pyridine-4-aldehyde and 5 ml. concentrated hydrochloric acid are heated to the boil under reflux. After the solution has been clarified with active charcoal, it is evaporated and the residue is digested with a little water. After suction filtration and drying, there are obtained 6.98 g. (29% of theory) of the desired product in the form of colourless crystals of the hydrochloride; m.p.>280° C.
