PROCESS FOR THE PREPARATION OF A 1-PHENYL-2-OXA-TRIAZATRIDECAN-13-OIC ACID FOR USE AS A DIAGNOSTIC CONTRAST AGENT

摘要

The present invention refers to a process for preparing a compound of formula (I) through a carboxymethylation reaction occurring in the presence of a suitable alkylating agent and of a base, without the need of monitoring the pH of the reaction environment. The compound of formula (I) is a useful intermediate in the preparation of diagnostic contrast agents for MRI techniques.
