Reduction of fused bicyclic impurities in triiodinated x-ray contrast media |
| abstract |
The present disclosure generally relates to an improved process for alkylating a triiodo-substituted arylamide to form a compound suitable for use as an X-ray contrast agent. More particularly, the present disclosure is directed to such a process that limits the formation of fused bicyclic impurities, such as Impurity G, in the alkylation reaction mixture. |
