Epsztajn, J. published the artcileApplication of organolithium and related reagents in synthesis. Part XII. Synthesis of phenyl- and pyridylpyridopyridazinones and their derivatives, Formula: C10H14N2O, the publication is Monatshefte fuer Chemie (1993), 124(5), 549-58, database is CAplus.
The pyridazinones I (R = 2-pyridyl, Ph), II (R = 3-pyridyl, Ph) and III (R = 4-pyridyl, Ph) were prepared from ketoamides, e.g. 4-benzoyl-N,N-diisopropyl-3-pyridinecarboxamide (IV) and 3-benzoyl-N,N-diisopropyl-4-pyridinecarboxamide (V), and hydrazine hydrate. From ketoamides IV and V in addition to the expected pyridopyridazinones II (R = Ph) and III (R = Ph) also aminopyridopyridazines VI and VII were formed. The pyridopyridazinones were alkylated with alkyl iodides.
Monatshefte fuer Chemie published new progress about 530-40-5. 530-40-5 belongs to amides-buliding-blocks, auxiliary class Pyridine,Amine,Amide, name is N,N-Diethylisonicotinamide, and the molecular formula is C10H14N2O, Formula: C10H14N2O.
