Reaktionsschritte
A solution of 4.56 g of the ester obtained in 30 ml of benzene was hydrogenated over 0.45 g of a 10% palladium/charcoal under a hydrogen atmosphere at room temperature for 4 hours. After filtration of the catalyst, the reaction mixture was concentrated under reduced pressure to obtain 4.26 g of 2-cyano-3-phenylpropionic acid ethyl ester as a colorless oil.
