Versuchsvorschrift

5.7 g. of N-butyl-acetamidine are dissolved in 300 ml of anhydrous ethanol, whereupon 7 g. of 5-diazo-1,2,3-triazole-4-carboxamide are added at 25° C. within half an hour. After 3 hours the solution is clarified with activated charcoal and evaporated in vacuo. The residual thick oil is admixed with 40 ml of anhydrous ethylacetate and the crude product (9.7 g. melting at 150° C. decomposition) is recrystallized from a mixture of 110 ml of acetone and 40 ml of anhydrous ethanol. Thus 6.1 g. of 5-[3-n-butyl-3-(alpha-iminoethyl)-1-triazeno]-1,2,3-triazole-4-carboxamide melting at 159°-160° C. (decomposition) are obtained.
