-
Paragraph 0024-0035, (2020/12/14)
The invention relates to a synthesis method of 1-(2-dimethylaminoethyl)-1H-5-sulfydryl-tetrazole. The synthesis method comprises the following steps: (1) with sodium N, N-dimethyl ethylenediamine dithiocarboxylate and sodium azide as raw materials, water as a reaction solvent and an alkaline solution as a catalyst, carrying out heating reflux, and after the reaction is finished, neutralizing the reaction solution with an acid to obtain a crude 1-(2-dimethylaminoethyl)-1H-5-sulfydryl-tetrazoleproduct; and (2) recrystallizing the crude 1-(2-dimethylaminoethyl)-1H-5-sulfydryl-tetrazole product obtained in step (1) through a recrystallization solution to obtain the 1-(2-dimethylaminoethyl)-1H-5-sulfydryl-tetrazole finished product, wherein the recrystallization solution is a mixed solution ofmethylbenzene and water. The product prepared by the method has the advantages of high purity and high yield, the reaction process is safe, and the method is a green and environment-friendly synthesisprocess.
