Triethylamine → {3-[3-(2-Methoxy-ethyl)-cyclobutyl]-phenylethynyl}-triisopropyl-silane

Participants

Reaction Steps

In a CEM snap top microwave vial were combined 1-Bromo-3-[3-(2-methoxy-ethyl)-cyclobutyl]-benzene (0.340 gm 1.28 mmol), triisopropylsilylacetylene (0.29 g, 1.12 mmol), copper iodide (9 mg, 0.178 mmol), tetrakis(triphenylphosphine)palladium (29 mg, 0.088 mmol) and triethylamine (1.30 g, 12.8 mmol). The vial was quickly agitated then irradiated in a CEM Explorer™ microwave instrument for 30 minutes at 80° C. Purification by column chromatography (hexanes) afforded an oil 375 mg (80%). This material was used in next step without further characterization.
