Method for producing 5-methyl-1H-tetrazole

A method for producing 5-methyl-1H-tetrazole, the method comprising steps of:

• producing a mixture containing 5-methyl-1H-tetrazole by reacting a reaction mixture containing acetonitrile, an azide compound, a Lewis acid compound, and water;
• producing a concentrate from the mixture;
• and
• obtaining solid 5-methyl-1H-tetrazole by extracting the concentrate 3 to 5 times using ethyl acetate in an amount of 1 ml to 9 ml based on 1 mmol of the azide compound, and drying the extract.
