The nitrile on treatment with NaN3, NH4Cl and DMF yielded the corresponding tetrazole. The tetrazole obtained was characterized by IR, 1H NMR, EI-MS and elemental analysis. The compound was screened for antimicrobial activity against Staphylococcus aureus, Escherichia coli, Candida albicans and Aspergillus niger.The results of the study show that the compound possesses fairly good antimicrobial activity against the test organisms.
