Versuchsvorschrift

To a stirred solution of methyl 5-chloro-2-methoxybenzoate (23.1 g, 0.115 mol) in dioxane (300 mL) was added 2.5N NaOH (230 mL). The resulting mixture was stirred at room temperature for 4 hours, concentrated, diluted with H2O, and acidified with 2N HCl. 19.70 g (91%) of the desired product was collected by filtration as a white solid.
