Reaction Steps
3,5-Bis-(acetoxyacetamido)-2,4,6-triiodo-(2,3-diacetoxypropyl)benzene, Example 71 a, was alkylated using 2-bromoethyl acetate in the presence of cesium carbonate according to the general procedure given in Example 25a. The reaction product was purified by HPLC to give the two products. 5-Acetoxyacetamido-3-[N-(2-acetoxyethyl)-acetoxyacetamido]-2,4,6-triiodo-(2,3-diacetoxypropyl)benzene was isolated in 12% yield.
