sodium (CAS NO.: ), with its systematic name of , 2-((2-carboxyphenyl)amino)-4-chloro-, disodium salt, could be produced through many synthetic methods.

Following is one of the synthesis routes:
ichlorobenzoic acid (I) is condensed with anthranilic acid (II) in the presence of K₂CO₃, powdered Cu and a small amount of I₂ in refluxing isoamyl alcohol, to produce Lobenzarit sodium.
