실험 절차

A stirred solution of [6-chloro-3-methyl-4-(4,4,5,5-tetra methyl-[1,3,2]-dioxaborolan-2-yl)-naphthalen-2-yl]-acetic acid methyl ester (0.2 g, 0.53 mmol) in dimethoxyethane (5 mL) was purged with argon for 5 minutes at room temperature. Tetrakis(triphenylphosphine)palladium(0) (0.031 g, 0.027 mmol), crude 1-bromo-4-(4-(trifluoro-methoxy)phenylsulfanyl)benzene (0.334 g) and 1.0 M aqueous sodium bicarbonate (5 mL, 5 mmol) were added simultaneously to the reaction mixture under argon. The reaction mixture was refluxed for 2 hours and then brought to room temperature. Water was added and the resulting mixture was extracted twice with ethyl acetate. The combined organic extracts were washed with water and brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to give the crude product, which was finally purified using flash chromatography (0-3% ethyl acetate in hexanes) to obtain {6-chloro-3-methyl-4-[4-(4-trifluoromethoxyphenylsulfanyl)-phenyl]-naphthalen-2-yl}-acetic acid methyl ester (0.127 g, 44%) as a solid.
