## 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
## Abstract The 7‐chloro‐3‐(2‐chlorobenzyl)‐ and 7‐chloro‐3‐(2‐fluorobenzyl)‐1,2,3‐triazolo[4,5‐__d__]pyrimidines (**1** and **4**), by nucleophilic replacement with some hydrazides, gave the corresponding 7‐hydrazidoderivatives (**2a‐e** and **5a‐e**). These, by heating in Dowtherm, underwent an i
