Using General Procedure F; 1-ethynyl-4-(1-benzyloxycyclopropyl)-3-methyl-benzene (Intermediate 76, 90.0 mg, 0.34 mmol) and methyl-(4-iodophenyl)-acetate (Reagent B, 95.0 mg, 0.34 mmol) in triethylamine (5 mL) was treated with copper(I)iodide (22.0 mg, 0.11 mmol) and sparged with argon for 5 minutes. Dichlorobis(triphenylphosphine)palladium(II) (80 mg, 0.11 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (2-4% EtOAc—hexanes) afforded 90.0 mg (71%) of the title compound as a pale-yellow oil.
