Procedure
N,N'-bis[2,4,6-triiodo-3,5-bis(2,3-diacetoxypropylaminocarbonyl)phenyl]-urea (4.0 g, 2.26 mmol) was dissolved in a 1:1 mixture of water and methanol (25 ml) containing NaOH (1.44 g, 36 mmol). After stirring for 6 h at 40° C., the solution was treated with a strongly acidic ion exchange resin (Amberlyst 15), the solvent was separated and evaporated to give pure product. Yield: 3.24 g (100%).
