Reaction Steps
A mixture of tributylamine (2.66 ml, 18.39 mmol), palladium diacetate (53 mg, 0.24 mmol), formic acid (0.205 ml, 5.32 mmol) and 5-bromo-2-[1-(3-iodo-5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yloxymethyl)-vinyl]thiophene (2.57 mg, 4.84 mmol) in acetonitrile (75 ml) was heated at 60° C. for 4 h. The reaction medium was concentrated in a rotary evaporator under vacuum at 40° C. Water and ethyl ether were added. After decantation, the organic phase was washed twice with 20 ml of water, dried over magnesium sulfate and concentrated in a rotary evaporator under vacuum at 40° C.
