Abstract
A new method for the synthesis of pyrimido-[4,5-e][1,2,4]triazines from 5,5-dibromopyrimidines was studied. Condensation of dibromopyrimidines (1a, b) with aminoguanidine or its analogues gave the 6,8-dioxo series (5) of the pyrimidotriazine, and aminodibromopyrimidines (2a, b) gave the 6-amino-8-oxo series (6).
