A new three-step synthetic method was designed to prepare 2,6-diamino- 3,5-dinitropyrazine 1-oxide (LLM-105) with an overall yield of 43.5%, using iminodiacetonitrile, triethylamine and hydroxylamine hydrochloride as the starting materials, and involved nitrosylation, cyclization and nitration. The structure of LLM-105 was characterized by FTIR, 1H NMR spectroscopy and elemental analysis. The crucial...
