Synthesis of 5-phenyltetrazole

Preparation of 5-phenyltetrazole

Preparation of 5-phenyltetrazole

Preparation of 5-phenyltetrazole

To the solution of 10.3 g (100 mmole) of benzonitrile in 50 ml of DMF 7.8 g (120 mmole) of sodium azide and 6.4 g (120 mmole) of ammonium chloride are added. The obtained mixture is stirred for 5 h at 100° C. The sodium chloride is filtered off, and DMF is removed in vacuo. The solid residue is dissolved in 100 ml of water, acidified with concentrated hydrochloric acid to pH < 2 and obtained crystals of 5-phenyltetrazole are separated by  filtration.
