Versuchsvorschrift

Methanol (500 ml) and Pd/activated charcoal 5% (wet, 3.45 g) are added to 2-[(2-hydroxyethyl)amino]-3-nitrobenzonitrile (69 g, 0.333 mol). The suspension is shaken in a Parr apparatus under 20 psi pressure of hydrogen for 1 hour. The mixture is then filtered on Celite and evaporated to dryness to give the desired material (62.7 g). This product is used in the next step without further purification.
