Procedure

A solution of 2-(o-nitrostyryl)pyridine (94.3 g., 0.42 mole) in 400 ml. of ethanol is reduced on a Parr hydrogenation apparatus employing 2 g. of 10% palladium on carbon catalyst to provide 2-(o-aminophenethyl)pyridine, m.p. 59°-61° C. The isolation of the pyridine product is carried out in the usual manner by collecting the catalyst and evaporating the ethanolic solvent.
