Versuchsvorschrift

1 g (5 mmol) of (4-nitrophenyl)glycine is dissolved in 20 ml of ethanol, 5 ml of water and 2.5 ml (2.5 eq) of 5N hydrochloric acid in a 250 ml glass reactor (Paar apparatus). 1 g of palladium-on-charcoal (50% moisture and 10% active) is then introduced. The mixture is hydrogenated under a pressure of approximately 2.76×105 Pa for 1 hour 30 minutes at a temperature of 20° C. After filtering through celite, the filtrate is evaporated to dryness. A white solid is obtained which is taken up in 50 ml of acetone, filtered and dried under vacuum at 40° C. 0.95 g of a white powder is obtained.
