Reaction Steps

The nitrotetrazoloquinoxaline (23) (1.84 g, 8.51 mmol) was added to a mixture of 15 ml of glacial AcOH and 20 ml of 30% H2O2 and heated at 85° C. in an oil bath for 16 hours. Upon cooling, the mixture was diluted with H2O (50 ml) and the precipitate collected by filtration. Recrystallization from 40 ml of 50% aq. DMF gave 1.29 g of yellow flocculant needles comprising 7-nitrotetrazolo[1,5-a]quinoxalin-4(5H)-one (24). This nitrotetrazoloquinoxalinone (3.00 g, 12.9 mmol) was added to conc. H2SO4 (40 ml) and treated with KNO3 (1.43 g, 14.1 mmol) with warming to 50° C. under N2. The mixture was poured onto 600 ml of ice-H2O, and a light yellow solid collected by filtration and washed with H2O, yielding 7,8-dinitrotetrazolo[1,5-a]quinoxalin-4(5H)-one (25).
