{circle around (4)}: A mixture comprising 3.3 g of 4-(4′-n-dodecylcarbonyloxyphenylcarbonyloxy)-1-benzyloxybenzene, 0.3 g of palladium/carbon and 20 g of ethyl acetate was stirred for 6 hours under hydrogen atmosphere. Then, palladium/carbon was filtered off, followed by distilling off ethyl acetate from the filtrate. The resultant residue was recrystallized from toluene, whereby 2.5 g of 4-(4′-n-dodecylcarbonyloxyphenylcarbonyloxy)phenol was obtained in the form of a colorless crystal.
