We would like to report the synthesis of a derivative of the new heterocyclic ring system pyrrolo[4,3,2-de]pyrimido[4,5-clpyridazine. The reaction of 4-chloro-5-cyano-7-(g-D-ribofuranosyl)pyrrolo[2,3-dlpyrimidine (I) (3) with methylhydrasine should have furnished 5-cyano-4-(N-l-methylhydrazino)-7-(B
