Versuchsvorschrift

The above prepared 3-cyclopropyl-5-methoxy-benzoic acid methyl ester (0.221 g, 1.07 mmol) was dissolved in 3.6 ml of THF/ethanol=1/1 and treated with 1.79 ml of aq. NaOH (3M, 5 eq.). The mixture was stirred for 1.5 h at ambient temperature and was then poured onto crashed ice/AcOEt/HCl dil.; the organic layer was washed with water, dried over sodium sulfate, and evaporated to dryness to leave 0.202 g of the title compound as white solid.
