Vorschrift

A 900 mg portion of 4-tetradecylphenol, acetate was heated at 70° C. under argon and 720 mg of aluminum trichloride was added portionwise. After 2 hours the temperature was raised to 120° C. and the mixture was heated at this temperature for 45 minutes. The mixture was then cooled, diluted with chloroform, washed with 50% aqueous hydrochloric acid then water and dried. The solvents were removed and the residue recrystallized from ethermethanol, giving 850 mg of the desired compound, mp 38.5°-39.5° C.
