反应条件: temp:50.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 1-Chloroethyl benzyl carbonate (prepared according to Synthesis 1986, 627), (2.36 g, 11.0 mmol) was added at room temperature to a solution of potassium 5-(N-acetylamino)-3-(N-acetyl-N-methylamino)-2,4,6-triiodobenzenecarboxylate (6.66 g, 20 mmol) and sodium iodide (0.15 g, 1 mmol) in dry DMF (50 ml). After stirring at 50° C. for 7 hours and at room temperature for 7 days the solvent was removed at reduced pressure. The residue was dissolved in chloroform (100 ml) and washed four times with a saturated sodium hydrogen carbonate solution and twice with water. After treatment with magnesium sulfate the solution was evaporated to dryness. Yield: 6.8 g. Purity by HPLC: 97% 1H-NMR(DMSO-d6): delta=1.64 (CHCH3); 1.66(N(CH3)COCH3); 2.05 (NCOCH3); 5.23 (CH2); 7.00 (CH); 7.30-7.45(arom.); 10.12 ppm (NH). was removed at reduced pressure The residue was dissolved in chloroform (100 ml) washed four times with a saturated sodium hydrogen carbonate solution After treatment with magnesium sulfate the solution was evaporated to dryness
