실험 절차

5-Bromo-2-hydroxy-benzoic acid (5 g, 23.04 mmol) was reacted with 4-trifluoromethyl phenyl boronic acid (6.56 g, 34.5 mmol) as desribed in general procedure D. The crude product was then was then purified by silica gel column chromatography (ethyl acetate:hexanes from 20:80 to 60:40) to afford 4.5 g of the 4-hydroxy-4′-trifluoromethyl-biphenyl-3-carboxylic acid as a white solid.
