Versuchsvorschrift

A solution of Ethyl 2-(3-hydroxy-4-nitrophenyl)propanoate (900 mg, 3.76 mmol) in THF/ethanol (1:1, 30 mL) was slowly added 10% Pd/C (93 mg) at room temperature. The mixture was hydrogenated for 1 hour at 46 psi and then filtered with celite pad and washed with EtOAc. The filtrate was concentrated in vacuo. The residue was purified by column chromatography eluting with n-Hexane/EtOAc=2/1.
