Synthesis method of 2-methyl-1, 2, 4-triazole-3-amine

The invention relates to a synthesis method of 2-methyl-1, 2, 4-triazole-3-amine, and mainly solves the technical problem that no suitable industrial synthesis method exists at present. The method comprises the following three steps: 1, reacting a compound 1 in a solvent 1, 4-dioxane with added N, N-dimethylformamide dimethyl acetal to obtain a compound 2; 2, reacting the compound 2 with triphenylphosphine and diisopropyl azodicarboxylate in methanol to obtain a compound 3; and 3, reacting the compound 3 with sodium hydroxide in methanol and water to obtain a final compound 4, wherein the reaction formula is described in the specification. 本发明涉及一种2-甲基-1,2,4-三唑-3-胺的合成方法，主要解决目前没有适合工业化合成方法的技术问题。本发明分三步，第一步，首先由化合物1在溶剂1，4-二氧六环中加入N,N-二甲基甲酰胺二甲基缩醛反应得到化合物2，第二步，化合物2与三苯基膦，偶氮二羧酸二异丙酯在甲醇中反应得到化合物3，第三步，化合物3与氢氧化钠在甲醇和水中反应得到最终化合物4，反应式如下：。
