A mixture of 5 g (28.4 mmol) of 1-phenyl-1-cyclohexanol, 5.35 g (56.8 mmol) of phenol and 250 mg (1.32 mmol) of toluenesulfonic acid monohydrate was stirred at 85° C. under nitrogen atmosphere for 4 hours. The material was allowed to cool to room temperature, diluted with ethyl acetate, washed with saturated sodium bicarbonate, water and brine. The resulting solution was dried (Na2SO4), filtered and concentrated to a white solid which was heated under high vacuum to remove residual phenol. The resulting residue was purified by flash chromatography on silica gel, eluting with methanol/dichloromethane to provide 5.64 g (22.4 mmol) of 4-(1′-(phenyl)cyclohexyl)phenol.
