Participants

Reaction Steps

Using General Procedure F; 1-ethynyl-4-(1-methoxycyclopropyl)-benzene (Intermediate 61, 120.0 mg, 0.56 mmol) and methyl-(4-iodophenyl)-acetate (Reagent B, 154.0 mg, 0.56 mmol) in triethyl amine (6 mL) was treated with copper(I)iodide (35.0 mg, 0.19 mmol) and sparged with argon for 5 minutes. Dichlorobis(triphenylphosphine)palladium(II) (130 mg, 0.19 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (2-8% EtOAc-hexanes) afforded 140.0 mg (78%) of the title compound as an orange solid.
