Versuchsvorschrift

To a solution of 5-[Acetyl-(3-amino-2-hydroxy-propyl)-amino]-N-(2,2-dimethyl-[1,3]dioxolan-4-ylmethyl)-N′-(dimethyl-[1,3]dioxolan-4-ylmethyl)-2,4,6-triiodo-isophthalamide (2.0 g, 2 mmol) in DMF (4 mL) were added triethylamine (0.45 g, 4 mmol, 2 eq) followed by acetic acid {3-chlorocarbonyl-5-[(2,2-dimethyl-[1,3]dioxolan-4-ylmethyl)-carbamoyl]-2,4,6-triiodo-phenylcarbamoyl}-methyl ester (1.85 g, 2 mmol, 1 eq). The reaction mixture was stirred at room temperature overnight under nitrogen. The mixture was diluted with ethylacetate and washed with water. The organics were collected, dried over MgSO4, filtered and evaporated to dryness. The product was purified by silica column chromatography eluting with ethylacetate/MeOH to give acetic acid {3-[3-(acetyl-{3,5-bis-[(2,2-dimethyl-[1,3]dioxolan-4-ylmethyl)-carbamoyl]-2,4,6-triiodo-phenyl}-amino)-2-hydroxy-propylcarbamoyl]-5-[(2,2-dimethyl-[1,3]dioxolan-4-ylmethyl)-carbamoyl]-2,4,6-triiodo-phenylcarbamoyl}-methyl ester (725 μmol, Yield=33%).
