| titleOfInvention | Preparation of intermediates of x-ray contrast agents |
| abstract | The present invention relates to a process for the preparation of iodinated X-ray contrast agents, in particular their core intermediates. The present invention particularly relates to an intermediate in the industrial production of non-ionic X-ray contrast agents, 5-acetamido-N,N'-bis(2,3-dihydroxypropyl)-2,4,6- Triiodoisophthalamide (Compound A) or N,N'-bis(2,3-dihydroxypropyl)-5-formamido-2,4,6-triiodoisophthalamide (Compound C) It relates to an improved manufacturing method of. More specifically, the present invention provides a method for deacylating the acylated hydroxyl groups of the intermediate compounds of these compounds A and C. |
