Reaction of 4-Aryl-1,2,4-triazines with Hydrazine

The action of hydrazine on 3,5-dioxo-4-aryl-2,3,4,5-tetrahydro-1,2,4-triazines gave 4-amino-3,5-dioxo-2,3,4,5-tetrahydro-1,2,4-triazines.The intermediates of this reaction were isolated and shown to be α-ketoacidhydrazide 4-arylsemicarbazones and not the α-ketoanilidecarbohydrazones.The relative rates of cyclization of the latter isomeric derivatives provide a support for a proposed intermediates which were not isolated in the reaction of 3-mercapto and 3-methylmercapto-4-aryl-5-oxo-4,5-dihydro-1,2,4-triazines with hydrazine.
