Abstract

m[p - {b - [p (1,1,3,3 - Tetramethyl - n - butyl)-phenoxy] ethoxy} benzoylamino] benzoylacet-31, 51-dicarbomethoxy-anilide is prepared by reacting dimethyl-m-amino-isophthalate with methyl m-nitrobenzoyl-acetate and reducing the nitro group in the product to give 3-amino-benzoylaceto-31,51-dicarbomethoxy-anilide, and then reacting this with p-{b -[1,1,3,3-tetramethyl-n-butyl)-phenoxy] ethoxy} benzoyl chloride obtained from the free acid (see Specification 774,421) and thionyl chloride. Similar compounds are obtained when 2-hydroxy-4-amino-benzoic acid methyl ester, methyl m-amino-phenoxyacetate or dimethyl aminoterephthalate is used instead of dimethyl-m-amino-iso-phthalate, or if methyl p-nitrobenzoylacetate is used instead of the meta compound. The esters may be subsequently hydrolysed to the sodium salts. m-(p-Hexadecyloxy-benzoylamino)benzoyl-aceto - 31,51 - dicarbomethoxy - anilide is similarly prepared from 3-amino-benzoyl-aceto-31,51-di carbomethoxy-anilide (see above) and p-(n-hexadecyloxy) benzoyl chloride (from the free acid and thionyl chloride).
