Versuchsvorschrift

5 g of crude (2R)-2-bromo-3-phenylpropionic acid (HPLC: 92.5%) were dissolved in 20 ml of ethyl acetate and treated at room temperature with 2.7 ml of triethylamine. After a stirring time of about 150 minutes, no precipitation of the product was to be observed. An HPLC analysis of the solution showed that the (2R)-2-bromo-3-phenyl-propionic acid had reacted completely to give cinnamic acid.
