実験手順

Using General Procedure F; 1-ethynyl-4-(1-isopropoxycyclopropyl)-benzene (Intermediate 66, 114.0 mg, 0.57 mmol) and ethyl-4-iodo benzoate (Reagent A, 731.0 mg, 0.63 mmol) in triethylamine (8 mL) was treated with copper(I)iodide (36.0 mg, 0.19 mmol) and sparged with argon for 5 minutes. Dichlorobis(triphenylphosphine)palladium(II) (133 mg, 0.19 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (2-4% EtOAc-hexanes) afforded 151.0 mg (76%) of the title compound as an orange solid.
