Procedure

The compound 14 (1.86 g), 0.896 g of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC), and 0.029 g of 4-dimethylaminopyridine (DMAP) were dissolved in 300 ml of methylene chloride. After the compound 16 (3.04 g) was then added and stirred at room temperature for 24 hours, the reaction solution was moved into a separating funnel, and was washed twice with 100 ml of 10% aqueous potassium hydrogen sulfate solution, twice with 100 ml of aqueous saturated sodium hydrogen carbonate solution, twice with 100 ml of ion-exchange water, and twice with 100 ml of saturated brine. After the methylene chloride phase collected was dehydrated with magnesium sulfate, the desiccant agent was removed by filtration, and the solvent of the filtrate was distilled away under reduced pressure. The reaction mixture was purified by chromatography, and 2.63 g of 11-(p-tolyloxy)undecyl 3-(tritylthio)propioate 17, which was a white solid, was obtained.
