Versuchsvorschrift
To a mixture of 2-(2-fluoro-3-methoxyphenyl)acetonitrile (6.7 g, 40.6 mmol) in water (40 mL) and methanol (40 mL), sodium hydroxide (3.2 g, 81.1 mmol) was added. The resulting mixture was stirred at 60° C. for 5 h. After cooling to room temperature, methanol was evaporated under reduced pressure. The residue was acidified with 10% HCl until pH 5. The resulting precipitate was collected by filtration and dried to afford the title compound (6.3 g).
