New Methods for Preparing an Intermediate of Contrast Medium and Methods for Preparing Contrast Medium

A manufacturing method of the present invention reduces treatment processes when manufacturing a contrast medium or an intermediate thereof, and thus generates less waste solvent, thereby being eco-friendly and capable of significantly reducing a manufacturing cost. Therefore, the manufacturing method of the present invention is economical and suitable for mass production since the production cost of the contrast medium can be greatly reduced.

METHOD FOR PREPARING TRIIODOISOPHTHALAMIDE X-RAY CONTRAST MEDIA IOVERSOL

The present invention relates to a method for producing an X-ray contrast agent ioversol. More specifically, the present invention relates to the method for manufacturing the X-ray contrast agent ioversol in which an inorganic base, chloride and the like are added to 5-(2-hydroxyacetamido)-N,Nandprime;-bis(2,3-dihydroxypropyl)-2,4,6-triiodoisophthalamide(chemical formula 9), followed by performing an N-alkylation reaction, thereby being able to easily separating and removing inorganic salts generated during reaction without ion exchange resin treatment while shortening an existing manufacturing time, and thus being able to minimize reaction impurities.COPYRIGHT KIPO 2020

Preparation method of ioversol

The present invention provides a novel preparation method of ioversol. The method comprises the following steps: adding a protection group to 5-hydroxyacetylamino-N,N'-bis(2,3-dihydroxypropyl)-2,4,6-triiodo-1,3-benzenedicarboxamide, conducting an alkylation reaction under an alkaline condition, and carrying out deprotection, so as to prepare ioversol. According to the preparation method disclosedby the invention, hydroxyl is protected before alkylation, so that the generation of ioversol rearrangement impurities (impurity II) in the alkylation preparation process is effectively controlled, the refining difficulty of a finished product is reduced, the refining yield is increased, and the preparation method is more suitable for industrialization.
