Versuchsvorschrift
Combine methyl 3,5-dimethoxy-4-ethoxy-benzoate (2.13 g, 9,421 mmol) and methanol (30 mL). Add a 1M aqueous solution of sodium hydroxide (50 mL, 50 mmol). After 1 hour, acidify the reaction mixture using a 1M aqueous hydrochloric acid solution, extract with ethyl acetate. Dry the organic layer over MgSO4, filtered and evaporated in vacuo to give the title compound.
