The invention relates to a synthesis method of 2-methyl-1,2,4-triazole-3-amine, and mainly solves the technical problem that there is no suitable industrial synthesis method at present. The present invention is divided into three steps. In the first step, first, compound 1 is added to solvent 1, 4-dioxane by adding N,N-dimethylformamide dimethyl acetal to react to obtain compound 2. In the second step, compound 2 is obtained. 2 is reacted with triphenylphosphine and diisopropyl azodicarboxylate in methanol to obtain compound 3. In the third step, compound 3 is reacted with sodium hydroxide in methanol and water to obtain final compound 4. The reaction formula is as follows: . |
