Versuchsvorschrift
Add 10% Pd/C (0.5 g) to a solution of 3 nitro-5-(trifluoromethyl) pyridin-2-amine (1.0 g, 4.83 mmol) in ethanol (10 mL). Hydrogenate the mixture at a pressure of 50 psi for 5 hours. Filter the mixture through celite, evaporate to dryness under reduced pressure to obtain 5-trifluoromethyl-pyridine-2,3 diamine.
