실험 절차

4-(3,7,11,15-Tetramethyl-2-hexadecenyl)-1,3-benzenediol (2.00 g: 5.14 mmole) was dissolved in ethanol (10 ml), a suspension of Raney's nickel W4 in ethanol (15 ml), was added thereto and then the mixture was reciprocatively shaken at 70° to 85° C. and a hydrogen pressure of 70 to 80 atm. for 2 days. After removing Raney's nickel by filtration, the filtrate was concentrated and the concentrate was chromatographed through a silica gel column. Thus, 1.30 g of the title compound was recovered from the fractions eluted with hexane-ethyl acetate (5:1). Yield=65%.
