Reaction Steps
A flask was charged with bis(triphenylphosphine)palladium(II)chloride (0.042 g, 0.060 mmol) and copper(I) iodide (0.023 g, 0.120 mmol) under nitrogen atmosphere. THF (4.6 mL) was added, followed by 2-bromo-1-iodo-3-methylbenzene (0.594 g, 2 mmol), triethylamine (2.3 mL, 16.50 mmol) and 3,3-dimethylbutyne (0.251 mL, 2.040 mmol). The reaction mixture was allowed to stir at RT overnight. The reaction mixture was filtered through a plug of silica gel and the plug was rinsed with Et2O. The solvent was removed under reduced pressure and the remaining residue was purified by flash chromatography (0-2% EtOAc/hexanes). 2-Bromo-1-(3,3-dimethylbut-1-ynyl)-3-methylbenzene was obtained as a light-yellow clear oil.
