실험 절차

One hundred ml. of triethylorthoformate was mixed with 8.98 g. of 2-hydrazinoquinoxaline. The mixture was stirred at reflux and cooled as in the example above, and 9 g. of crude product was collected. After recrystallization from ethanol, the product was identified as s-triazolo[ 4,3-a]quinoxaline, m.p. 238°-39° C. The final yield was 5 g.
