実験手順

A 5 g. portion of 2-hydrazinoquinoxaline was stirred at reflux temperature in acetic acid for 3 hours. The reaction mixture was then cooled, and was evaporated to dryness under vacuum. The product was found to melt at 210°-12° C. without purification, and was identified as 1-methyl-s-triazolo[ 4,3-a]quinoxaline by NMR analysis and elemental microanalysis, the results of which follow.
