실험 절차

The above prepared (2-{2-[2-((2R,3R,4R,5R,6R)-4,5-diacetoxy-6-acetoxymethyl-3-acetylamino-tetrahydro-pyran-2-yloxy)-ethoxy]-ethoxy}-ethoxy)-acetic acid (2.820 g, 5.246 mmol) and (S)-6-amino-2-((S)-2,6-diamino-hexanoylamino)-hexanoic acid benzyl ester hydrochloride (preparation see below, 0.829 g, 1.749 mmol) were dissolved in a mixture of 32 ml, of CH2Cl2 and 3.2 mL of DMF, treated successively with Hünig's base (2.096 ml, 12.25 mmol), 1-hydroxy-7-azabenzotriazole (0.714 g, 5.248 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (1.006 g, 5.248 mmol), and stirred over night at ambient temperature. All volatiles were removed i.V., and the crude reaction mixture purified by preparative HPLC (38 runs, Gemini, 5μ, C18) to give after lyophilization 1.650 g of the title product as white powder. MS (ISP): 1945.8 [M+Na]+. NMR (600 MHz, DMSO).
