A reaction mixture comprising 3.0 g of 4-benzyloxy-4′-(trifluoromethoxy)biphenyl, 0.1 g of palladium hydroxide and 30 ml of ethyl acetate was filled with hydrogen gas, and stirred at room temperature for 8 hours. The reaction mixture was filtered, and the solvent of the filtrate was evaporated away. The resulting residue was recrystallized from heptane, and 1.5 g of 4-hydroxy-4′-(trifluoromethoxy)biphenyl was obtained. m.p.: 140-140.5° C.
