摘要：
The invention is directed to a process for preparing a 5-substituted tetrazole, the process comprising the step of reacting a nitrile with an inorganic azide salt in an aromatic hydrocarbon solvent in the presence of an amine salt. According to the invention, a 5-substituted tetrazole can be produced in a high yield with ease and safety using inexpensive raw materials while the reaction is easily controlled to inhibit a side reaction.
