Reaction Steps
Using General Procedure D; (4-bromo-2-methyl-benzyloxy)-trimethylsilane (Intermediate 134, 550.0 mg, 2.01 mmol) in triethylamine (8 mL) was treated with copper(I)iodide (38.0 mg, 0.20 mmol) and then sparged with argon for 5 minutes. Trimethylsilyl acetylene (1.05 g, 10.6 mmols) was then added followed by dichlorobis(triphenylphosphine)palladium(II) (142.0 mg, 0.20 mmol). The resulting reaction mixture was heated to 70° C. for 5 days. The title compound (380.0 mg, 65%) was isolated by chromatography (0-2% EtOAc—hexanes) as an orange oil.
