반응 단계
Following General Procedure D and using 4-bromo-2,6-di-t-butyl-phenol (1.43 g, 5 mmol), triethyl amine (1 5 mL), anhydrous tetrahydrofuran (15 mL), copper(I)iodide (0.06 g, 0.31 mmol), trimethylsilyl acetylene (4.9 g, 50 mmol) and dichlorobis(triphenylphosphine)palladium(II) (0.18 g, 0.26 mmol) followed by flash column chromatography over silica gel (230-400 mesh) using hexane as eluent, the title compound was obtained (1.35 g, 90%).
