実験手順
Succinimido 3-(triphenylmethylthio)propanoate (4.06 mg, 9.12 mmol) was added to a 0° C. solution of 2-{2-[2-(2-aminoethoxy)ethoxy]ethoxy}ethanol (C. Bertozzi and M. Bednarski, J. Org. Chem. 1991, 56, 4326-4329) (9.12 mmol) in dichloromethane (20 mL). The solution was stirred at room temperature for 2 days and concentrated ammonium hydroxide (1 mL) was added. After 20 minutes, the mixture was filtered and the filtrate was subjected to an extractive workup. The organic layer were dried over sodium sulfate and concentrated under reduced pressure. The crude product was purified by HPFC on silica gel (gradient elution with 2-19% CMA in chloroform) to provide 3.95 g of N-(2-{2-[2-(2-hydroxyethoxy)ethoxy]ethoxy}ethyl)-3-(tritylthio)propanamide as a colorless oil.
