Nitrile of the starting acid 1-(4-aminophenyl)-4-benzoyl-5-phenyl-1H-pyrazole-3-carboxylic acid was also obtained. While cyclocondensation reactions of two acids and nitrile mentioned hydrazines lead to pyrazolo[3,4-d]pyridazine derivatives, the reaction of starting acid with 2-hydrazino-pyridine provided hydrazono-pyrazole acid derivative.eninfo:eu-repo/semantics/closedAccessCyclic Oxalyl CompoundsPyrazolePyrazolopyridazineQuinolineArticle8N/AN/A12011208WOS:000223706400012
