Potassium Fluoride → 4-[1-(4'-Isopropyl-2,6-dimethyl-biphenyl-4-yloxy)-2-methyl-propyl]-benzoic acid methyl ester

Participants

Reaction Steps

Isomer 1 of 4-[1-(4-bromo-3,5-dimethyl-phenoxy)-2-methyl-propyl]-benzoic acid methyl ester (500 mg, 1.28 mmol), potassium fluoride (223 mg, 3.84 mmol), 4-isopropylphenyl boronic acid (419 mg, 2.56 mmol) and tetrakis-(triphenylphosphine)palladium (148 mg, 0.128 mmol) are placed in a flask. After the reaction is purged with N2 for several times, THF/H2O (20 ml/5 ml) is added. The resulting solution is refluxed overnight, loaded on silica gel, eluted with hexane and ethyl acetate to give the titled compound (510 mg).
