To 2,4,6-triiodo-5-amino-isophthalic acid dichloride (150 g; 0.252 mole) in DMAC (300 ml) is added acetyl chloride (80 ml; 4 times the theoretical amount). The mixture is stirred overnight in an ice-water bath. It is then poured over water (1.5 liter). The resulting material is then filtered and washed twice with water, after which it is dried in an oven at 45° C, to give 159 g of product (i.e., in a yield of 99%).
