実験手順

To the solution of isomer 1 of 4-[1-(4′-isopropyl-2,6-dimethyl-biphenyl-4-yloxy)-2-methyl-propyl]-benzoic acid methyl ester (510 mg) in methanol (10 mL) is added sodium hydroxide (5 N aqueous, 2 mL) and stirred for 4 h. The reaction mixture is concentrated and acidified by 5 N HCl (2 mL), extracted with ethyl acetate. Combined organic layers are washed with water and brine, dried over sodium sulfate. Concentration gives the title compound (450 mg) as a white solid.
