Reaction Steps
Using General Procedure F; 6-ethynyl-4,4-dimethyl-3,4-dihydro-2H-naphthalen-1-one (Intermediate 13, 190.0 mg, 0.96 mmol) and methyl-(4-iodophenyl)-acetate (Reagent B, 245.0 mg, 0.96 mmol) in triethyl amine (8 mL) was treated with copper(I)iodide (46 mg, 0.24 mmol) and sparged with argon for 15 minutes. Dichlorobis(triphenylphosphine)palladium(II) (168 mg, 0.24 mmol) was added and the reaction mixture was stirred overnight at room temperature. Column chromatography (10-20% EtOAc-hexanes) afforded 250.0 mg (75%) of the title compound as a pale-yellow solid.
