Reaction Steps
Following General Procedure D and using trifluoromethanesulfonic acid, 3-tertbutyl-phenyl ester (Intermediate 101, 2.54 g, 9.0 mmol), triethyl amine (2 mL), copper(I)iodide (0.63 g, 3.33 mmol), trimethylsilyl acetylene (5 mL, 36 mmol) and dichlorobis(triphenylphosphine)palladium(II) (1.6 g, 2.25 mmol) followed by flash column chromatography over silica gel (230-400 mesh) using 10% ethyl acetate in hexane as the eluent, the title compound was obtained as a brown oil that was used as such for the next step.
