Versuchsvorschrift

Ethyl 3-nitro-4-(trifluoromethyl)benzoate (11.58 g, 44 mmol) was taken up in EtOH (150 ml) and vacuum purged. Then, under a nitrogen atmosphere, Pd/C (1.15 g) was added. The mixture was stirred at RT overnight under a hydrogen atmosphere using a balloon. The reaction was filtered through a pad of celite and the filtrate reduced under reduced pressure to give ethyl 3-amino-4-(trifluoromethyl)benzoate a white solid.
