실험 절차

To a solution of tert-butyl [2-(4-bromophenyl)ethyl]-[(2R)-2-(3-chlorophenyl)-2-hydroxyethyl]carbamate (560 mg) and methyl 6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-naphthoate (461 mg) in N,N-dimethylformamide (5.6 ml) were added [1′,1′-bis(diphenylphosphino)ferrocene]-palladium(II) dichloride dichloromethane complex (151 mg), 1,1′-bis(diphenylphosphino)ferrocene (102 mg) and 2M sodium carbonate (2.0 ml) at room temperature, and the mixture was stirred at 80° C. for 4 hours. The resulting mixture was poured into water and the aqueous layer was extracted with ethyl acetate. The organic layer was washed successively with water three times and brine, dried over anhydrous magnesium sulfate, and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (hexane/ethyl acetate=2/1) to give methyl 6-[4-[2-[(tert-butoxycarbonyl)[(2R)-2-(3-chlorophenyl)-2-hydroxyethyl]amino]ethyl]phenyl]-2-naphthoate (514 mg).
