実験手順
{circle around (4)}: A mixture comprising 2.0 g of (S)-4-[4′-(1″-methylnonylcarbonyloxy)phenyloxycarbonyl]-1-benzyloxybenzene, 0.2 g of palladium/carbon and 10 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 hexane, whereby 1.4 g of (S)-4-[4′-(1″-methylnonylcarbonyloxy)phenyloxycarbonyl]phenol was obtained in the form of a colorless crystal.
