実験手順

Chloromethyl phenylacetate (1.0 2 g, 5.5 mmol) (Intermediate 4) in dry DMF (50 ml) is added dropwise at 50° C. to a solution of cesium 5-(N-acetylamino)-3-(N-acetyl-N-methylamino)-2,4,6-triiodobenzenecarboxylate (3.80 g, 5.0 mmol) and sodium iodide (37 mg, 0.25 mmol) in dry DMF (70 ml). The precipitate is removed by filtration after stirring for 4 hours and the solvent is removed at reduced pressure. The residue is dissolved in chloroform (50 ml) and washed four times with a saturated sodium hydrogen carbonate solution. After drying with magnesium sulfate the solvent is removed at reduced pressure to give the title compound:
