Investigations on the synthesis and properties of N-phenyl derivatives of 1,4-dioxo (1,4,5-trioxo) - 1,2,3,4-tetra (1,2,3,4,5,6-hexa) hydropyrido- [3,4-d] pyridazines and allied compounds

2-(1-Piperidino)- and 2-(4-methyl-l-piperazinyl)-6-methyl-3,4- pyridinedicarboximides react with N-phenylhydrazine yielding N-phenylamino- 3,4-pyridinedicarboximides. The same reaction with 1,6-dimethyl-2-oxo-1,2- dihydro- and 2-chloro-6-methyl-3,4-pyridi
