Versuchsvorschrift
1.2 g (5 mmol) of ethyl (3-ethoxy-2-oxocyclohex-3-en-1-yl)(oxo)acetate were dissolved in 20 mL of ethanol and 25 mL (5.2 mmol) of hydrazine hydrate 98% were added dropwise. The solution was stirred at room temperature for 5 hours, then heated at 60° C. for further 5 hours. The solvent was removed in vacuo and the residue taken up with diethyl ether and the resulting precipitate collected by filtration giving 0.8 g of the title compound, that was employed in the next step without any further purification.
