Reaction Steps

A solution of 0.5 g (1.83 mmol) 1-chloro-3-ethoxalylamino-4-nitrobenzene in 15 ml dimethylformamide was hydrogenated at atm. pressure by using 0.5 g Ra-Ni as a catalyst. The residue was stirred with ethanol to give 0.13 g (30%) of 6-chloro-1-hydroxyquinoxaline-2,3(1H,4H)-dione. M.p. decomp. 1H-NMR (DMSO-d6): 11.8 (1H, broad s), 7.17 (3H, m). MS (m/e): 212 (M30 , 60%).
