Reaction Steps
Following General Procedure D and using 3-bromo-benzoic acid isopropyl ester (Intermediate 135, 1.25 g, 5.14 mmol), triethyl amine (12 mL), copper(I)iodide (0.078 g, 0.41 mmol), trimethylsilyl acetylene (4 mL, 28.16 mmol) and dichlorobis(triphenylphosphine)palladium(II) (0.288 g, 0.41 mmol) followed by flash column chromatography over silica gel (230-400 mesh) using 3% ethyl acetate in hexane as the eluent, the title compound (1.25 g, 94%) was obtained as an orange oil.
