Versuchsvorschrift

49.5 g (0.38 mol) of 3-(3-pyridyl)-acrylonitrile is dissolved in 428 ml of ethanol, 9.5 g of 10% Pd/C is added and hydrogenated under normal pressure. After the requisite hydrogen absorption, it is filtered off, and the filtrate is concentrated by evaporation in a vacuum. Chromatography (CH2Cl2→CH2Cl2/acetone 1:4) yields 38.3 g (76%) of 3-(3-pyridyl)propionitrile.
