Vanillin has been used as a chemical intermediate in the production of pharmaceuticals and other fine chemicals.The two intermediates; assigned as intermediates I and II; were prepared by using vanillin and 1-butylbromide or 2-chloroacetic acid; respectively. The condensation of intermediates with 2; 3- -diaminopyridine gave azomethines. Their structure was established by using elemental microanalysis; as well as UV/Vis; FTIR and 1H-NMR spectra. Synthesized compounds were tested for their antifungal activity against Candida albicans; Candida lipolytica and Sacharomyces cerevisiae
