Reaction Steps
Following General Procedure B and using 2-[(cyclopropyl-methyl-amino)-methyl]-4-ethynyl-benzoic acid isopropyl ester (Intermediate 122, 0.05 g, 0.18 mmol), 2-fluoro-4-iodo phenylacetic acid methyl ester (0.07 g, 0.24 mmol), triethyl amine (2 mL), copper(I)iodide (0.04 g, 0.21 mmol) and dichlorobis(triphenylphosphine)palladium(II) (0.07 g, 0.11 mmol) followed by flash column chromatography over silica gel (230–400 mesh) using 15–16% ethyl acetate in hexane as the eluent, the title compound was obtained as an oil (0.04 g, 50%).
