Versuchsvorschrift
To a solution of acetic acid 2-(3-nitro-phenyl)-ethyl ester (15 g, 71.7 mmol) (from Example 3a supra) in ethyl acetate (150 mL), was added 10% palladium on carbon (1.5 g) (Aldrich). This mixture was hydrogenated at room temperature on the Parr apparatus at 50 psi for one hour. The reaction mixture was filtered over a bed of Celite® and washed with ethyl acetate. The filtrate was concentrated under reduced pressure to give acetic acid 2-(3-amino-phenyl)-ethyl ester. (Yield 12.81 g, 71.48 mmol, 99%).
