Abstract

The present invention relates to a preparation method of diethylenetriaminepentaacetic acid (DTPA) derivatives comprising preparing penta-alkyl DTPA and selectively hydrolyzing to obtain tetra-alkyl DTPA using metal ion as catalyst. The method of the invention uses two reaction steps to prepare DTPA derivatives having unit activity.
