Versuchsvorschrift

Propan-1-amine (136 mmol) was added to a solution of ethyl 2-(2,4-dinitrophenyl)-3-oxobutanoate (135 mmol) in chloroform (500 mL). The reaction mixture was maintained for 12 h at rt and was concentrated. The residue was purified by chromatography 20/1 hexane/ethyl acetate to provide ethyl 2-(2,4-dinitrophenyl)acetate in 99% yield as a brown oil.
