Reaction Steps

5-(2,2-Dimethyl-1,3-dioxolane-4-carbamido)-3-acetoxymethyl-N-(2,3-diacetoxypropyl)-2,4,6-triiodobenzamide (0.80 g, 9.16 mmol) was dissolved in methanol (7 ml) and potassium carbonate (0.17 g, 12,3 mmol) was added. The mixture was stirred at room temperature for 17 h. The mixture was filtered and pH of the filtrate was adjusted to 1 using aqueous 5M hydrochloric acid, and the mixture was stirred for further 5 h at room temperature. The reaction mixture was then evaporated to a solid residue, which was purified by preparative HPLC. Yield: 0.41 g (49%) of a white freeze dried product.
