実験手順

To 25.8 mmol 5-acetyl-2-isopropoxy-benzoic acid methyl ester in 100 ml THF was added 400 mmol 2 M aq NaOH, and the mixture was heated at 80° C. for 2 h. The mixture was then cooled to RT and extracted twice with ether. The aqueous phase was acidified with 15% aq hydrochloric acid and extracted 3 times with ethyl acetate. The combined organic phases were dried with Na2SO4. Evaporation in vacuo followed by trituration in ether afforded the title compound. MS (m/e): 221.2 ([M−H]−, 100%)
