Cyclization of hydrazones (1d, 3d, 5d, 7d) afforded compounds (1h, 3h, 5h, 7h) containing 6-azauracile and also 1,2-dihydro-quinoxaline-2-one rings in their molecules. The starting aminoderivative (1b) was prepared by the re By diazotization of 3-(4-aminophenyl)-1,2-dihydro-quinoxaline-2-one (2b), 3-(2-aminophenyl)-6,7-dimethyl-1,2-dihydro-quinoxaline-2-one (1b), its 3-(4-aminophenyl)-isomer (3b), 3-(2-aminobenzyl)-1,2-dihydro-quinoxaline-2-one (4b), its 3-(4-aminobenzyl)-isomer (6b), 3-(2-aminobenzyl)-6,7-dimethyl-1,2-dihydro-quinoxaline-2-one (5b) and its 3-(4-aminobenzyl)-isomer (7b) and by azo coupling of formed diazonium salts with ethyl cyanoacetylcarbamate, 3-methyl-1,2-dihydro-quinoxaline-2-one, 3,6,7-trimethyl-1,2-dihydro-quinoxaline-2-one and 3-methyl-6,7-dichloro-1,2-dihydro-quinoxaline-2-one, corresponding hydrazones with one 1,2-dihydro-quinoxaline-2-one ring (1d, 3d, 5d, 7d) and hydrazones with two 1,2-dihydro-quinoxaline-2-one rings (3e-3g, 4e-4g, 5e-5g,6e-6g, 7e-7g) were prepared.
