Phenylboronic Acid → 1-[2-hydroxy-4-(4-methoxybiphenyl-3-yl)-4-methyl-2-trifluoromethylpentyl]-1H-quinolin-4-one

A mixture of 1-[4-(5-bromo-2-methoxyphenyl)-2-hydroxy-4-methyl-2-trifluoromethylpentyl]-1H-quinolin-4-one (200 mg, 0.4 mmol), Pd(OAc)2 (9 mg, 0.04 mmol), DCyBPP ((2-dicyclohexylphosphino)biphenyl, 28 mg, 0.08 mmol), KF (93 mg, 1.6 mmol) in toluene/THF (3/2 mL) at room temperature was treated with phenylboronic acid (98 mg, 0.8 mmol). The reaction mixture stirred overnight at room temperature and filtered through CELITE® filter aid. The residue was diluted with EtOAc (20 mL), washed with aqueous NaOH (11.0M, 10 mL), water, and brine (10 mL). The organic phase was dried over sodium sulfate, filtered, and solvent was evaporated in vacuo. The residue was purified silica gel chromatography and then by reverse phase HPLC to provide 1-[2-hydroxy-4-(4-methoxybiphenyl-3-yl)-4-methyl-2-trifluoromethylpentyl]-1H-quinolin-4-one as white solid.
