Versuchsvorschrift

5-Amino-2,4,6-triiodo-isophthaloyl dichloride was dissolved in dimethyl acetamide (DAMC) and a solution of acetoxyacetylchloride (2 eq) in DMAc was slowly added with efficient stirring. The reaction mixture was stirred overnight and the following day, the mixture was slowly poured into stirred ice water. The precipitate was filtered off and dried to give the desired material. The structure was confirmed by 1H NMR (CDCl3, 300 MHz): 10.43 (brs, 1H); 4.71 (s, 2H); 2.11 (s, 3H)
