Procedure

1.28 mL (9.23 mmol) of triethylamine, 1.06 g (5.56 mmol) of p-toluenesulfonyl chloride, 43 mg (0.45 mmol) of trimethylamine hydrochloride were added to a solution of 1.50 g (4.63 mmol) of 5,9,13,17-tetramethyloctadec-4-en-1-ol in dry methylene chloride (9 mL) was added, at 0° C., sequentially. After being stirred for 3 hours at room temperature, 0.14 mL (1.1 mmol) of N,N-dimethyl-1,3-propanediamine was added to the reaction mixture at 0° C. After being stirred for 3 hours, the mixture was diluted with ethyl acetate. The resulting solution was washed with water, 1M hydrochloric acid, saturated sodium bicarbonate aqueous solution, and saturated brine, successively, and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated to obtain (5,9,13,17-tetramethyloctadec-4-enyl)tosylate as a crude product.
