Abstract
The fully unsubstituted pyrazolone (= 2-pyrazolin-5-one, which is tautomer to 1H-pyrazol-3-ol and 1H-pyrazol-5-ol) was prepared from hydrazine hydrate and methyl (2E)-3-methoxyacrylate in almost quantitative yield. Detailed spectroscopic data (1H NMR,13C NMR,15N NMR, MS) for this compound are presented.
