Heat-resistant energetic compounds are of great importance in the field material chemistry. Here, we report a practical synthesis series fused-ring via combination 1,2,3-triazine N-oxide and 2,4,6-trinitroaniline moieties. Starting from known compound 4,6-diamino-2-chloropyrimidine-5-carbonitrile (1), nucleophilic substitution followed by one-step nitration introduced three nitro groups onto benzene ring moiety, simultaneously. The resulting 4-7 exhibited high decomposition temperature (Td > 250 °C) as well relatively good detonation properties low sensitivities.
