A solution of ethyl 4-iodo-benzoate (55.2 g, 0.2 mol) in triethylamine (800 mL) was purged with argon. Copper iodide (1.1 g) and bis(triphenylphosphine)palladium(II) dichloride (7.0 g) were then added and the mixture was purged again. Trimethylsilylacetylene (42 mL, 0.3 mol) was then added at 0° C. for 30 minutes and the resulting mixture stirred at room temperature for 1 hour. The mixture was concentrated, triturated in hexane and filtered. The filtrate was concentrated to give ethyl 4-(2-trimethylsilylethen-1-yl-benzoate (51.5 g, 100% crude) as a black oil.
