Synthesis and reactions of a new series of 1,2,4-triazolo[4,3-c] quinazolines

3-Ethoxycabonyl-1,2,4-triazolo[4,3-c]quinazoline (2) has been synthesized in excellent yield by the condensation of 4-hydrazinoquinazoline (1) with diethyl oxalate and was converted into 3-carbohydrazide 3. The later product was treated with potassium thi
