Procedure

Using General Procedure F; cyclopropyl-ethyl-(4-ethynyl-2-methyl-benzyl)-amine (Intermediate 161, 300.0 mg, 1.41 mmols) and methyl-(4-iodophenyl)-acetate (Reagent B, 388.0 mg, 1.41 mmols) in triethylamine (8 mL) was treated with copper(I)iodide (67.0 mg, 0.35 mmol) and sparged with argon for 15 minutes. Dichlorobis(triphenylphosphine)palladium(II) (246 mg, 0.35 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (5-7% EtOAc-hexanes) afforded 270.0 mg (53%) of the title compound as a pale-yellow oil.
