Reaction Steps

A solution of 4-bromo-1-ethoxalylamino-2-nitrobenzene (1.0 g, 3.2 mmol) in 50 ml of N,N-dimethylformamide was hydrogenated at atmospheric pressure and room temperature in the presence of a small amount of Raney-Ni. The catalyst was removed by filtration, and the filtrate was evaporated to dryness. The residue was tritureted with ethanol affording 0.68 g (84%) of the title compound. M.p.>250° C. dec.; 1H-NMR (DMSO-d6): 6.98-7.63 (m. 3H ArH) appr. 11.9 (very broad s 1H NH): IR (KBr): 1700 cm-1 ; MS (m/e): 256 (M+, 62%), 258 (M+2)+, 58%).
