A PROCESS FOR THE PREPARATION OF N,N'-BIS(2,3- DIHYDROXYPROPYL)-5-((HYDROXYACETYL)METHYLAMINO)-2,4,6-TRIIODO-1,3-BENZENDICARBOXAMIDE

摘要

A novel process for the preparation of N,N'-bis[2, 3-dihydroxypropyl] -5-[ (hydroxyacetyl) methylamino]-2, 4,6-triiodo-1, 3-benzenedi carboxamide of formula (I), commonly known as lomeprol, a novel non-ionic contrast agent which shows very good safety and contrast effectiveness.
