Abstract
The synthetic route of 4,4′-dinitro-6,6′-dimethyl-2,2′-bipyridine N,N′-dioxide was designed with the aim to satisfied the need of bifuncional chelates of time-resolved fluorescence immunoassay.It was prepared from 2-amino-6-methylpyridine by diazotization,bromization and Ullmann's couple,oxidation,nitration.The structure of this product was determined by DSC,IR,element analysis and 1H NMR.The result proved the reliability of this product and the synthetic method.The reaction conditions were researched and the synthetic method was improved.So the methods simplify the handle process and increase the yield.
