Reaction Steps
A solution of 10.44 g (45.8 mmol) of (3R,7R)-3,7,11-trimethyldodecan-1-ol in 150 mL of anhydrous pyridine was stirred in an acetone-ice bath while 17.4 g (91.3 mmol) of p-toluenesulfonyl chloride was added in one portion. The mixture was stirred in the acetone-ice bath for 2 hr then kept at 0° C. for 40 hr before being quenched by the addition of 300 mL of ice-water. The product was isolated by extraction with 3×300 mL of ether. The ether extracts were combined, washed with 400 mL of cold 3N HCl and saturated brine, then dried (MgSO4), filtered and concentrated in vacuo. There was obtained 16.6 g (94.9%) of (3R,7R)-3,7,11-trimethyldodecyl p-toluenesulfonate.
