3,4,5-Tris(octadecyloxy)cyclohexylmethyl alcohol (68.5 g, 74.5 mmol) was dissolved in chloroform (700 ml), pyridine (26.9 ml, 0.33 mol), DMAP (903 mg, 7.39 mmol) and p-toluenesulfonyl chloride (44.9 g, 0.236 mol) were added, and the mixture was stirred for 5 days. The solvent was evaporated, and the residue was precipitated with acetonitrile (700 ml) and washed with acetonitrile (700 ml) to give 3,4,5-tris(octadecyloxy)cyclohexylmethyl tosylate (76.9 g, 71.6 mmol, 96%).
