Reaction Steps
Using General Procedure F; 4-ethynyl-1-(1-isopropoxycyclopropyl)-3-methyl-benzene (Intermediate 81, 80.0 mg, 0.13 mmol) and ethyl-4-iodo benzoate (Reagent A, 100.0 mg, 0.36 mmol) in triethylamine (5 mL) was treated with copper(I)iodide (25.0 mg, 0.13 mmol) and sparged with argon for 5 minutes. Dichlorobis(triphenylphosphine)-palladium(II) (91 mg, 0.13 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (2-4% EtOAc-hexanes) afforded 75.0 mg (56%) of the title compound as an orange solid.
