3-Cyano-4,6-diphenyl-2-(phenethylamino)pyridine

Abstract

Novel synthesis of a 2-amino-3-cyano-2,6-diphenyl pyridine by a one-pot multi-component reaction of 1,3-diphenylpropane-1,3-dione, malononitrile and phenethylamine in the presence of N-hydroxybenzamide and zinc chloride has been reported. The structure of the synthesized compound was assigned on the basis of its elemental analysis, 1H-NMR, 13C-NMR, IR and mass spectral data. X-ray structure analysis confirmed unambiguously the proposed structure. The photophysical properties (λAbs., λFlu.) in CH3OH, CH3CN, CH2Cl2 and the emission spectrum of the new compound in solution and in the solid state are reported.
