A mild and efficientsynthesis of N-acylhydrazones has been developed, applying a simple grindstone procedure, leading to a library of 51 examples exhibiting a broad variety of structural features, 21 of them described for the first time in this paper. This methodology works without any organic solvent under the catalysis of acetic acid at room temperature, promotes the formation of essentially pure

e)benzohydrazide (2), N'-(2-hydroxy-5-methylbenzylidene)-4-nitrobenzohydrazide (3) and 2-fluoro-N'-(2-hydroxy-5-methylbenzylidene)benzohydrazide (4), were prepared and structurally characterized by elemental analysis, IR and 1H NMR spectra, and X-ray single crystal determination. The xanthineoxidase inhibitory activities of the compounds were investigated. Among the compounds, N'-(3-methoxybenzyl
