A novel synthetic approach of 3,3'-azobis(6-amino-1,2,4,5-tetrazine) was firstly devised. Taking 3,6-bis(3,5-dimethylpyrazol-1-yl)-1,2,4,5-tetrazine as a primary material, DAAT was synthesized by high pressure ammonolysis and potassium permanganate oxidation. Compared with the four-step reaction in the literature, this new approach was reduced to two steps with a yield of 58.1%. The intermediate and DAAT were characterized by elemental analysis, IR and NMR spectra.

自行设计了3，3'-偶氮双(6-氨基-1，2，4，5-四嗪)新合成路线、采用3，5-双(3，5-二甲基吡唑-1-基)-1，2，4，5-四嗪为原料，由文献报道的4步反应缩减为2步，经高压氨解、高锰酸钾氧化合成了DAAT，总收率大幅提高，达到58.1%，并采用元素分析、红外光谱、核磁共振光谱等进行了结构表征。
