Procedure
To a solution of 0.5 g (~1.89 mmol) 8-fluoro-7-nitro[1,2,4]triazolo[4.3-a]quinoxaline-1,4(2H,5H)-dione in 10 ml dry N,N-dimethylformamide was added 0.4 g (~5.9 mmol) imidazole. The reaction mixture was stirred at 120° C. for 2h. Evaporation in vacuo gave the title compound as an oil, which was solidified by stirring with water. Yield: 0.34 g (58%). M.p.>300° C. decomp.
