Versuchsvorschrift

Palladium on carbon (10%, 50 mg) was added to a solution of 4-(2-nitrovinyl)benzoic acid methyl ester (228 mg) in 5 mL of ethyl alcohol and 2 mL of acetic acid. The reaction vessel was saturated with hydrogen and stirred under a 1 atm hydrogen atmosphere for 20 h. The vessel was saturated with nitrogen and filtered through celite. Evaporation of the solvents gave 205 mg of crude 4-(2-amino-ethyl)-benzoic acid methyl ester.
