Procedure

Equimolar mixtures of (p-chlorophenyl)-sulphonyl isocyanate and n-butylazide were dissolved at room temperature in toluene with a molar concentration of 0.6. 1-(p-chlorophenylsulphonyl)-4-n-butyl-2-tetrazolin-5-one was obtained, which was a white powder or a clear crystalline precipitate, according to whether the precipitation occurred fast or slow. The product had a melting range of 76.5°-77.5° C. The following results were obtained by elementary analysis:
