By nitration of ethyl malonate,ethyl 2,2-dinitroacetate was synthesized. The condensation with acetaldehyde in presence of N_aN₃ gave 4-methyl-5-nitro-1,2,3-trazole. 4-Amino-5-nitro-1,2,3-trazole (ANTZ) was finally synthesized by the process of oxidation,esterifies and recomposition. Their structures were confirmed by IR,NMR,DSC and elemental analysis. The best condition of oxidation reaction is 100 ℃,90 min,1：2 ratio of K₂CO₃ to 4-methyl-5-nitro-1,2,3-trazole.
