실험 절차

To 100 ml of benzyl chloride were added 15 g of 3,7,11,15-tetramethyl-2,6,10,14-hexadecatetraen-1-ol and 6.0 g of finely divided potassium hydroxide, and the resulting mixture was refluxed under stirring for 2 hours. The mixture was cooled and then to the mixture was added 1 liter of hexane. The hexane solution was then washed with water and concentrated. The concentrate was purified over a silica gel column to give 12 g of 1-benzyloxy-3,7,11,15-tetramethyl-2,6,10,14-hexadecatetraene (yield 61%).
