Vorschrift

A mixture of 14.6 g of 3-(octadecyloxy)-5-(3-phenoxypropoxy)benzoic acid phenylmethyl ester and 3 g of 10% palladium on carbon was shaken in a hydrogen atmosphere at room temperature for 2 hours. The catalyst was removed by filtration and the filtrate was concentrated to a solid which was recrystallized from ether-hexane to give 11.8 g (95% yield, mp 79°-81°) of 3-(octadecyloxy)-5-(3-phenoxypropoxy)benzoic acid.
