Abstract:
A series of novel 1,3,5-triazine derivatives bearing various aryl amine, 2-amino pyrazine and 4-hydroxy coumarin moieties as substituents have been synthesized by an easy and conventional method using sequential nucleophilic substitution of chlorine atoms of cyanuric chloride. The reaction of cyanuric chloride with 4-hydroxy coumarin in acetone using alkaline medium at 0-5°C was afforded compound 3 in good yield. Followed by reaction 3 with 2-amino pyrazine and then various aromatic amines have afforded target compounds 6a-n in good yields. All the newly synthesized compounds were characterized by using spectroscopic analysis and then examined for their ability to inhibit the two Grampositive bacteria (Bacillus subtilis and Staphylococcus aureus) Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa) and
one fungal species (Aspergillus niger) for biological interest.
