실험 절차

Using General Procedure D; benzyl-[1-(4-bromophenyl)-cyclopropyl]-methylamine (Intermediate 130, 90.0 mg, 0.28 mmol) in triethylamine (8 mL) was treated with copper(I)iodide (6.0 mg, 0.03 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) (20.0 mg, 0.03 mmol). The resulting reaction mixture was heated to 70° C. for 5 days. The title compound 80 mg (84%) was isolated by chromatography (0-2% EtOAc—hexanes).
