실험 절차

To a solution of 3-(3,5-difluoro-4-methyl-phenyl)-propionic acid butyl ester (6.960 g; 27.157 mmol) in MeOH (150 ml) and water (25 ml) was added at rt aq. 1N NaOH (68 ml; 68 mmol). The resulting solution was further stirred at rt for 1 h. MeOH was then removed under reduced pressure. Water (25 ml) was added, and the mixture was acidified with aq. 1N HCl (68 ml) in order to reach pH=2. DCM (150 ml) was added, and the layers were shaken and separated. The aq. layer was further extracted with DCM (50 ml). The mixed organic layers were dried over anh. MgSO4, filtered, and concentrated to dryness under reduced pressure. The product 3-(3,5-difluoro-4-methyl-phenyl)-propionic acid was obtained as a pale yellow solid which was further dried under HV (5.090 g; 94%). LC-MS: tR=0.86 min.; [M+H]+: no ionisation.
