In 200 g of ethanol were dissolved 86.5 g (0.5 mol) of 4-bromophenol and 22 g (0.55 mol) of sodium hydroxide. To the solution at 70° C., 121.8 g (0.55 mol) of n-decyl bromide was added dropwise. The solution was allowed to ripen for 4 hours and cooled to room temperature, after which 120 g of water was added. The oily matter was separated therefrom and concentrated by a rotary evaporator, followed by vacuum distillation (boiling point 143-145° C./0.5 Torr), yielding 90 g of 4-n-decyloxyphenyl bromide.
