Procedure

Following General Procedure B and using 2-(3-ethynyl-phenyl)-2-methyl-propionic acid ethyl ester (Intermediate 132, 0.10 g, 0.46 mmol), 2-fluoro-4-iodo phenyl acetic acid methyl ester (0.136 g, 0.46 mmol), triethyl amine (8 mL), copper(I)iodide (0.01 g, 0.05 mmol) and dichlorobis(triphenylphosphine)-palladium(11) (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 (0.15 g, 85%).
