Abstract

The present invention refers to a process for the preparation of S-(-)-5-[[2-(acetyloxy)-1-oxopropyl]-amino]-2,4,6-triiodo-1,3-benzenedic arboxylic acid dichloride of formula (I) comprising the reaction between S-(-)-[2-(acetyloxy)]propionic acid chloride and 5-amino-2,4,6-triiodo-1,3-benzenedicarboxylic acid dichloride, in an aprotic dipolar solvent and in presence of a halogenhydric acid.
