実験手順

To a solution of 17-azido-3,6,9,12,15-pentaoxaheptadecanamine (15 g, 50 mmol) in dichloromethane (100 mL) was added diglycolic anhydride (Acros, 6.4 g, 55 mmol). The reaction mixture was stirred overnight. The reaction was monitored by ESI-MS analysis, and more reagents were added to drive the reaction to completion. The solution was concentrated to give a yellow residue which was dissolved in water (250 mL). The product was isolated from the aqueous phase by continuous extraction with dichloromethane over night. Drying and evaporation of the solvent gave a yield of 18 g (85%). The product was characterized by ESI-MS analysis (MH+ calculated: 423.20; found 423.4). The product was used in the next step without further purification.
