Procedure

Following General Procedure B and using cyclopropyl-(3-ethynyl-4-methyl-benzyl)-methyl-amine (Intermediate 99, 0.095 g, 0.48 mmol), ethyl-4-iodo-cinnamate (Reagent 3, 0.144 g, 0.47 mmol), triethyl amine (13 mL), copper(I)iodide (0.019 g, 0.1 mmol) and dichlorobis(triphenylphosphine)palladium(II) (0.071 g, 0.1 mmol) followed by flash column chromatography over silica gel (230–400 mesh) using 5–20% ethyl acetate in hexane as the eluent, the title compound was obtained (0.14 g, 82%).
