A method for the production of l - 5 - (2 - acetoxy - propionyl - amino) - 2,4,6 - - - isophthalic acid dichloride triiodoisophthalic

摘要

improved process for the production of l - 5 - (2 - acetoxypropionylamino) - 2,4,6 - trijod - isophthalsu00e4ure - dichlorid through implementation of 5 amino 2,4,6 - trijod - isophthalsu00e4ure - dichlorid with l 2 - acetoxy - propionyl chloride in the presence of a lewis acid.
