The acetyl benzo[f]coumarin condensed with phenyl hydrazine to afford the corresponding phenyl hydrazone which cyclized into the pyrazolyl benzocoumarin under Vilsmeier reaction conditions. The pyrazolylaldehyde was used as starting material for synthesis of other heterocyclic compounds containing pyrazolylbenzocoumarin moiety. The ethyl benzo[f]coumarin carboxylate were subjected to react with other
