The condensation product of 2-hydrazinopyridine and phenacyl bromide in presence of anhydrous aluminium chloride undergoes interamolecular Friedel Crafts reaction to result 3-phenyl-1, 4-dihydroazacinnolines. These results were confirmed by an alternative method, i.e., NBS bromination of the condensation product of acetophenone and pyridylhydrazine and then cyclising in the presence of cyclising agent. The study of the spectral datas of 3-phenyl-1, 4-dihydroazacinnolines was recorded and compared which confirmed that 3-phenyl-1, 4-dihydroazacinnolines obtained in both cases are identical.
