Participants

Reaction Steps

A mixture of 413.0 g of the 2-(4-bromophenoxy)benzyl alcohol and 1290 ml of 48% hydrobromic acid is boiled under reflux for 4 hours, then cooled and poured onto 2000 ml of ice and water. The greenish oil that separates out is dissolved in 2000 ml of diethyl ether. The organic phase is washed twice with 400 ml of water and with 400 ml of a 1N aqueous sodium bicarbonate solution, dried over magnesium sulphate and concentrated by evaporation at 40° under 11 mm Hg. The 2-(4-bromophenoxy)benzyl bromide, obtained in the form of an oily residue, is used without purification.
