Abstract

Viene descritto un miglioramento ad un processo per la preparazione della bis-(1,3-diidrossipropilammide) dell'acido L-5-(2-acetossi-propionilammino)-2,4,6-triiodo-isoftalico per reazione tra dicloruro dell'acido L-5-(2-acetossi-propionilammino)-2,4,6-triiodo-isoftalico e 2-ammino-1,3-propandiolo in presenza di una base.An improvement to a process for the preparation of the bis- (1,3-dihydroxypropylamide) of the L-5- (2-acetoxy-propionylamino) -2,4,6-triiode-isophthalic acid by reaction between dichloride of the L-5- (2-acetoxy-propionylamino) -2,4,6-triiode-isophthalic acid and 2-amino-1,3-propanediol in the presence of a base.
