Participants

Reaction Steps

Into the same device as used in Example 1 were placed 6.58 g (0.065 mole) of triethylamine and 52 ml of toluene. To the mixture were added 3.19 g (0.033 mole) of concentrated sulfuric acid with stirring. Further added were 5.16 g (0.050 mole) of benzonitrile and 4.23 g (0.065 mole) of sodiumazide. The mixture was heated to a temperature from 95° to 100° C. to undergo a reaction for 7 hours. The same subsequent treatment as in Example 1 was conducted, giving 7.11 g (0.049 mole) of 5-phenyl-1H-tetrazole (yield 97.3% based on benzonitrile).
