Reaction Steps

Using General Procedure D; dibenzyl-[1-(4-bromophenyl)-cyclopropyl]-amine (Intermediate 125, 45.0 mg, 0.11 mmol) in triethylamine (8 mL) was treated with copper(I)iodide (10.0 mg, 0.05 mmol) and then sparged with argon for 5 minutes. Trimethylsilyl acetylene (0.35 g, 3.6 mmols) was then added followed by dichlorobis(triphenylphosphine)palladium(II) (35.0 mg, 0.05 mmol). The resulting reaction mixture was heated to 70° C. for 5d. The title compound 40 mg (88%) was isolated by chromatography (hexanes).
