Vorschrift

To 37.6 g (0.07 mol) of the 4-(6-decyloxy-2-naphthoyloxy)benzoic acid benzyl ester obtained in the first stage was added 3.76 g of 5% palladium/carbon, and further added 188 g of THF. Then, hydrogen gas was blown into the mixture. The resultant mixture was stirred overnight and filtered to obtain 30.6 g of 4-(6-decyloxy-2-naphthoyloxy)benzoic acid.
