Triethylamine → 2-[5-(3-Isopropyl-phenoxy)-4'-trifluoromethyl-biphenyl-3-yl]-4-methyl-pentanoic acid methyl ester

Participants

Reaction Steps

A mixture of 2-(5-hydroxy-4′-trifluoromethyl-biphenyl-3-yl)-4-methyl-pentanoic acid methyl ester (50 mg, 0.14 mmol), 3-isopropylphenyl boronic acid (45 mg, 0.27 mmol), copper acetate (26 mg, 0.14 mmol), triethylamine (57 μL, 0.4 mmol) and powdered 4 Å molecular sieves in DCM (1 mL) were stirred at room temperature for 2 days. The reaction mixture was concentrated in vacuo. Purification by flash chromatography (EtOAc:petroleum ether) give the title compound (32 mg, 48%).
