Hydrochloric Acid → 6-Methyltetrazolo[1,5-a]quinoxaline

Participants

Reaction Steps

A solution was made of 0.5 g. of 2-chloro-5-methylquinoxaline, 10 ml. of 0.1N HCl and 0.6 g. of sodium azide in 35 ml. of denatured ethanol. The reaction mixture was stirred for 6 hours at reflux temperature. When the mixture was allowed to cool, the product, 6-methyltetrazolo[1,5-a]quinoxaline, crystallized in 91 percent yield and was separated by filtration. The product had a melting point of 160°-62°C., and was identified by nuclear magnetic resonance analysis and elemental microanalysis, the results of which were as follows.
