반응 단계
N,N'-bis[2,4,6-triiodo-3-(2-hydroxyethylaminocarbonyl)-5-(1,3-dihydroxyprop-2-ylaminocarbonyl)-phenyl]urea (0.25 g, 0.18 mmol) was dissolved in water (5 ml) followed by 2M aqueous NaOH (2.1 ml) and, after 5 min, bromopropane-2,3-diol (0.196 ml) was added. The solution was stirred for 4 days, neutralized with a strongly acidic cation exchange resin and evaporated to dryness. Purification by preparative HPLC gave 38 mg (14%) of the product as a white solid.
