Abstract:

4,4′-Dibromo-6,6′-bis(N,N-bis(ethoxycarbonylmethyl)amino methyl)-2,2′-bipyridine was prepared from 4,4′-dinitro-6,6′-dimethyl-2,2′-bipyridine N,N-dioxide by esterification with trifluoroacetic anhydride and hydroxymethylation, bromine methylation with HBr, and methylation of amino hydrogen with diethyl iminodiacetate. The structure of this product was determined by DSC, IR, 1H NMR, HPLC and HRMS. The obtained product is an important intermediate for the synthesis of a bi-functional chelate, which could find applications in solid phase time resolved fluoroimmunoassay.

Key words: time-resolved fluorescence immunoassay, chelate, intermediate, dibromo-bis(bromomethyl)-bipyridine, dibromo-bis(N,N-bis(ethoxycarbonylmethyl)amino methyl)-bipyridine, synthesis
