Versuchsvorschrift
Methyl 3-cyano-4-methoxybenzoate (879 mg) was dissolved in tetrahydrofuran (8 mL) and water (4 mL), and lithium hydroxide monohydrate (772 mg) was added to the solution, and then the mixture was stirred at mom temperature for 1 hour. The organic solvent was distilled off under reduced pressure and acidified with 2N hydrochloric acid, and then the precipitated crystal was collected by filtration to obtain the title compound (754 mg) as a colorless crystal.
