Reaction Steps

To a solution of 6-(18-hydroxy-1-oxooctadecyl)-2,3-dimethoxy-5-methylphenol (1.4 g) in acetic acid (30 ml) are added 5% palladium-on-carbon (50% hydrous) (0.5 g) and 70% perchloric acid (0.05 ml), and catalytic reduction is carried out at atmospheric temperature and pressure. After the absorption of hydrogen has subsided, the catalyst is filtered off and the filtrate is concentrated under reduced pressure, whereupon a colorless oil is obtained. This product is dissolved in ether and the ether layer is washed with 5% aqueous solution of sodium hydrogen carbonate and dried over anhydrous sodium sulfate. The solvent is then distilled off and the resultant crude crystals are recrystallized from hexane. The above procedure yields 6-(18-acetoxyoctadecyl)-2,3-dimethoxy-5-methylphenol (1.4 g) as colorless needles, m.p. 53° C.
