PROCEDURE

实验过程

N,N'-bis[2,4,6-triiodo-3-(2-hydroxyethylaminocarbonyl)-5-(1,3-dihydroxyprop-2-ylaminocarbonyl)-phenyl]urea (0.27 g, 0.2 mmol) from Example 4 was dissolved in water (7 ml) containing 2M aqueous NaOH (1.0 ml) and 2-bromoethanol (0.084 ml, 1.2 mmol). After stirring for 20 h, the solution was neutralized with a strongly acidic cation exchange resin and evaporated to dryness. The residue was purified by preparative HPLC. Yield 138 mg (50%).
