Procedure
The procedure of Example I.D. was followed except the quinoxalin-2-one was converted to the 6-nitroquinoxalin-2-one by first dissolving in conc. H2SO4 and cooling in an ice bath, and adding KNO3 in 3 portions. The product was collected by conventional technique and subsequently converted to 2-hydrazino-6-nitroquinoxaline. This compound was reacted with triethylorthoformate as per Example I.D., yielding 7-nitro-1,2,4-triazolo[4,3-a]quinoxaline (16).
