Versuchsvorschrift

To a solution of 21.3 g (108 mmole) of ethyl N-(4-fluorophenyl)glycine in THF (100 mL) under nitrogen was added LiOH (5.44 g (130 mmol) monohydrate in 25 mL water. After 15 h the mixture was concentrated to half the volume and acidified to pH 3 with HCl. The precipitated solid was collected and washed with water (100 mL) to afford the title compound.
