Versuchsvorschrift
Another process for the preparation of 5-benzoyl-1-methyltetrazole is known from J. Amer. Chem. Soc. 1963, 85, 2967-2976. Benzyl cyanide is reacted with ammonium azide to give 5-benzyltetrazole and then oxidized with chromium trioxide to give 5-benzoyltetrazole. The methylation to 5-benzoyl-1-methyltetrazole takes place with diazomethane. This synthesis route is likewise disadvantageous as regards safety and economical aspects.
