Abstract
The 3,5-pyridine di-acylhyrazines has been prepared using esterification and hydrazinolysis of pyridine 3,5-dicarboxylic acid.And then condensation of 3,5-pyridine di-acylhyrazines with aromatic aldehydes produced corresponding hydrazones,then cyclodehydrated with acetic anhydride to afford the title compounds.Their molecule structures were characterized by 1H NMR,FT-IR and MS,the typical spectrum properties of them were discussed.
