Reaction Steps
Using General Procedure F; 1-ethynyl-4-(1-benzyloxycyclopropyl)-benzene (Intermediate 71, 60.0 mg, 0.20 mmol) and methyl-(4-iodophenyl)-acetate (Reagent B, 66.0 mg, 0.24 mmol) in triethylamine (5 mL) was treated with copper(I)iodide (15.0 mg, 0.08 mmol) and sparged with argon for 5 minutes. Dichlorobis(triphenylphosphine)palladium(II) (56 mg, 0.08 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (2-7% EtOAc-hexanes) afforded 64.0 mg (81%) of the title compound as a yellow oil.
