Reaction Steps
Using General Procedure D; 1-bromo-4-(1-isopropoxycyclopropyl)-benzene (Intermediate 64, 240.0 mg, 0.94 mmol) in triethylamine (8 mL) was treated with copper(I)iodide (18.0 mg, 0.094 mmol) and then sparged with argon for 5 minutes. Trimethylsilyl acetylene (0.70 g, 7.1 mmols) was then added followed by dichlorobis-(triphenylphosphine)palladium(II) (66.0 mg, 0.094 mmol). The resulting reaction mixture was heated to 70° C. for 5 days. The title compound (250.0 mg, 98%) was isolated by chromatography (0-3% EtOAc-hexanes) as an orange oil.
