4-Toluenesulfonyl chloride → HCID 86672634, compound

Participants

Reaction Steps

0.63 mL (4.6 mmol) of triethylamine, 0.87 g (4.6 mmol) of p-toluenesulfonyl chloride, and 20 mg (0.21 mmol) of trimethylamine hydrochloride were added to a solution of 1.0 g (4.2 mmol) of 4,8,12-trimethyltridec-3-en-1-ol in dry methylene chloride (3 mL) at 0° C., sequentially. After being stirred for 2 hours at room temperature, 0.10 mL (0.83 mmol) of N,N-dimethyl-1,3-propanediamine was added to the reaction mixture at 0° C. After being stirred for 30 min, 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 (4,8,12-trimethyltridec-3-enyl)tosylate as a crude product.
