A solution of 8.15 g (0.075 mol) of 1-chloro-2-methyl-2-propanol in 20 ml of ethanol is run over the course of 25 minutes into a solution, kept at about 60° C., of 15 g (0.068 mol) of p-(p-chlorophenoxy)phenol and of 3 g (0.075 mol) of sodium hydroxide pellets in 20 ml of water and 20 ml of ethanol. The mixture is heated to the reflux temperature for 2 hours and the ethanol is driven off under reduced pressure. The residue is extracted with diethyl ether and after drying and evaporation of the solvent gives 7.3 g of a yellow oil. This oil is purified by crystallisation from a mixture of cyclohexane and petroleum ether (1:2 by volume) followed by washing with 2 N NaOH. 4 g of a white powder which is insoluble in water are obtained.
