Versuchsvorschrift
The 4-nitrophenylhydrazone of ethyl 2-oxopentanoate (D29) (0.72 g, 2.60 mM) was heated to reflux for 16 h in concentrated hydrochloric acid. After cooling to room temperature the precipitated solid was filtered off. Chromatography on silica using dichloromethane as eluant gave the title compound as a yellow solid (0.22 g; 45%).
