Versuchsvorschrift

(RS)-2-Fluoro-4-phenyl-butyric acid methyl ester (0.39 g, 2 mmol) was added to a solution of KOH (0.56 g, 10 mmol) in EtOH (5 ml). After 1 hour stirring at room temperature. the reaction mixture was concentrated, diluted with H2O (5 ml), acidified to pH 1 with 2N HCl and extracted with CH2Cl2 (3 times). The combined organic phases were dried over Na2SO4, filtered and concentrated to provide (RS)-2-fluoro-4-phenyl-butyric acid (0.343 g, 92%) as a colorless oil MS: m/e=182.1 (M+).
