A Process for the Preparation of N,N'-Bis2,3-Dihydroxypropyl-5-HydroxyacetylMethylamino-2,4,6-Triiodo-1,3-Benzenedi Carboxamide

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.
