Reaction Steps
Using General Procedure D; (4-bromo-2-methyl-benzyl)-cyclopropyl-ethyl-amine (Intermediate 159, 620.0 mg, 2.31 mmols) in triethylamine (8 mL) was treated with copper(I)iodide (44.0 mg, 0.23 mmol) and then sparged with argon for 15 minutes. Trimethylsilylacetylene (1.04 g, 10.6 mmols) was then added followed by dichlorobis-(triphenylphosphine)palladium(II) (162.0 mg, 0.23 mmol). The resulting reaction mixture was heated to 70° C. for 5 days. The title compound (650.0 mg, 98%) was isolated by chromatography (1-4% EtOAc—hexanes).
