반응 단계
A solution of 500 mg of 2,3,4-triacetoxy-1-{2-[2-(2-aminoethoxy)ethoxy]acetyl}5 hydroxypentyl acetate 23, 1.15 g of [2-(2-carboxymethoxyethoxy)ethoxy]acetic acid, 400 μl of diisopropylcarbodiimide and 288 mg of hydroxybenzotriazole in 20 ml of methylene chloride is stirred at room temperature for 12 h. The reaction solution is concentrated and separated by HPLC (Knauer Eurospher-100-10-C18, water (0.1% trifluoroacetic acid)/acetonitrile (0.1% trifluoroacetic acid)=80/20->10/90). This gives 24: C28H45NO18 (683.67) MS (ESI) 684 (M+H)
