Reaction Conditions

Reaction Steps

To a solution of Pd(PPh3)4 (542 mg) and TEA (4 mL) in DMF (16 mL) were added 1-bromo-4-isobutylbenzene (1 g) and ethynyl(trimethyl)silane (553 mg) at room temperature, followed by stirring at 60° C. for 4 hours. To the reaction liquid was added 1 M hydrochloric acid, followed by extraction with ether. The insoluble materials were filtered through celite. The organic layer was washed with brine, dried over MgSO4, and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane) to obtain [(4-isobutylphenyl)ethynyl](trimethyl)silane (459 mg) as a yellow liquid.
