실험 절차

N,N'-Bis[2,4,6-triiodo-3-(2-hydroxyethylaminocarbonyl)-5-(2,3-dihydroxypropylaminocarbonyl)-phenyl]urea (0.353 g, 0.257 mmol) was dissolved in a mixture of water (8 ml) and 2M aqueous NaOH (0.9 ml) together with 1-bromo-2,3-dihydroxypropane (0.136 ml, 1.55 mmol). After stirring at room temperature for 160 h, the solution was neutralized using a strongly acidic cation exchange resin. After evaporation, the residue was purified using preparative HPLC. Yield: 100 mg (27%) of the product as a white solid.
