実験手順
To a mixture of tert-butyl [2-(4-bromophenyl)ethyl]-[(2R)-2-hydroxy-2-(3-pyridyl)ethyl]carbamate (500 mg), [3-isobutyl-4-(methoxycarbonyl)phenyl]boronic acid (336 mg), [1,1′-bis(diphenylphosphino)feffocene]palladium(II) dichloride (48.5 mg) and 1,1′-bis(diphenylphosphino)ferrocene (16.4 mg) in N,N-dimethylformamide (3.75 ml) was added 2.0M aqueous sodium carbonate solution (2.08 ml) and the mixture was stirred at 90° C. for 3 hours. After cooling to room temperature, the mixture was partitioned between ethyl acetate (30 ml) and water (30 ml). The organic layer was separated, washed with brine (30 ml) and dried over magnesium sulfate. Filtration followed by evaporation under reduced pressure gave a crude product which was purified by column chromatography on silica gel (hexane/ethyl acetate=1/1 to 1/3) to give methyl 4′-[2-[[tert-butoxycarbonyl]-[(2R)-2-hydroxy-2-(3-pyridyl)ethyl]amino]ethyl]-3-isobutyl-4-biphenylcarboxylate (395 mg) as a yellow solid (foam).
