실험 절차

A mixture of methyl 3-[4-[(3-bromobenzyl)oxy]phenyl]propanoate (0.5 g, 1.43 mmol), 4-chloro-2-methylphenylboronic acid (0.30 g, 1.72 mmol), tetrakis(triphenylphosphine)palladium(0) (0.083 g, 0.072 mmol), sodium carbonate (0.46 g, 4.29 mmol), water (5 mL), ethanol (5 mL) and toluene (25 mL) was stirred under an argon atmosphere at 90° C. for 16 hrs. The reaction mixture was cooled, diluted with ethyl acetate, washed with water and saturated brine, dried and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=10/1-4/1) to give the title compound (0.50 g, yield 88%) as a colorless oil.
