실험 절차

To a solution of 3-bromo-4-isopropoxy-benzoic acid isopropyl ester (5.32 g, 17.7 mmol, 1 eq.) in EtOH (100 mL), 1M aq. NaOH soln. (80 mL) was added. The resulting solution was heated at 80° C. for 18 hours, then concentrated in vacuo. The resulting aq. layer was carefully acidified with 2N aq. HCl soln. The mixture was extracted with DCM (3×100 mL). The comb. org. phases were dried over MgSO4 and concentrated in vacuo to give 3-bromo-4-isopropoxy-benzoic acid. The product was used without further purification.
