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 overnight. 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.
