Reaction Steps
A mixture of 40.0 g of 1,6-bis(4-methoxyphenyl)hexane of Example 2, 150 ml of HBr (48%) and 150 ml of glacial acetic acid was refluxed for 5 hours. It was concentrated by evaporation to give a dark brown semi-solid. This was dissolved in ether, washed with water, dried over anhydrous magnesium sulfate and concentrated to give 28.0 g of dark brown semi-solid.
