Reaction Steps

A mixture of 1-(trans-4-heptylcyclohexyl)acetylene (28.40 mmol), 2′,3-difluoro-4-iodobiphenyl (28.40 mmol), tetrakis(triphenylphosphine)palladium(0)dichloromethane (0.85 mmol), copper iodide (1.43 mmol), and diethylamine (200 ml) is stirred for 4 hrs at room temperature. The reaction mixture obtained is extracted with toluene (200 ml) twice. The extract is washed with water (150 ml) three times and dried over anhydrous magnesium sulfate. The toluene solution is concentrated under reduced pressure, purified by silica-gel chromatography, and further recrystallized to give the titled compound.
