Reaction Steps

Following General Procedure D and using 4-bromo-2,6-di-t-butyl-phenol (1.43 g, 5 mmol), triethyl amine (15 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%).
