INTERMEDIATE COMPOUNDS AND PROCESSES FOR THE PREPARATION OF QUINOLINE DERIVATIVES SUCH AS LAQUINIMOD SODIUM

摘要

The present invention relates to processes for the preparation of quinoline-3 -carboxamide derivatives, such as sodium 5-chloro-3-(ethylphenylcarbamoyl)-l-methyl-2- oxo-l,2-dihydroquinolin-4-olate (Laquinimod sodium). The present invention further relates to intermediates formed in such processes.
