## Abstract Some new 1,2,3‐triazolo[4,5‐__e__]‐1,2,4‐triazolo[3,4‐__c__]pyrimidmes were prepared starting from the corresponding 1,2,3‐triazolo[4,5‐__d__]pyrimidines __via__ the formation of the 1,2,4‐triazole ring. Thus suitable hydrazino derivatives 6 were condensed with triethyl orthoformate, tr
