Procedure

Following General Procedure B and using 2-(3-ethynyl-phenyl)-2-methyl-propionic acid ethyl ester (Intermediate 132, 0.101 g, 0.47 mmol), 4-iodo phenyl acetic acid methyl ester (0.129 g, 0.47 mmol), triethyl amine (8 mL), copper(I)iodide (0.01 g, 0.05 mmol) and dichlorobis(triphenylphosphine)palladium(II) (0.035 g, 0.05 mmol) followed by flash column chromatography over silica gel (230-400 mesh) using 10-15% ethyl acetate in hexane as the eluent, the title compound was obtained as an oil (0.14 g, 82%).
