Three components; ethyl cyanoacetate, ethyl amines, and methyl propionylacetate were condensed using solid supports in microwave to give 1,4-diethyl-2,6-dioxo-1,2,5,6-tetrahydropyridine-3-carbonitrile (9) that was then coupled with aromatic diazonium salts to give the corresponding arylhydrazono-1,4-diethyl-2,6-dioxo-1,2,5,6-tetrahydropyridine-3-carbonitrile disperse dyes, 10a-g. Structures of the afforded compounds were confirmed by (IR, NMR, EI/MS) and one of them was further confirmed by X-ray crystallography (10g). Fastness properties of the reported dyes were intensively examined against light, perspiration and washing fastness, exhibiting moderate, very good and excellent fastness levels, respectively. The antimicrobial activity of the dyes were tested against different bacterial strains of Gram positive and Gram negative characteristics, and yeast, at where most of them showed promising activities against such test organisms.
