The synthesis of 8H-diimidazo[1,5-a:2′,1′-c][1,4]benzodiazepine 6, a novel nitrogen-containing tetracyclic ring, is reported starting from 5H-imidazo[2,1-c][1,4]benzodiazepine 7. Reaction of this compound with nitromethane and subsequent reduction of the obtained nitromethyl derivative 8 afforded 11-aminomethyl-10,11-dihydro-5H-imidazo[2,1-c][1,4]benzodiazepine 9. Treatment of the latter compound with
