A mixture of 14.6 g. of 3-amino-5-nitrobenzoic acid and 17.1 g. of 3,6,9-trioxadecanoic acid chloride in 200 ml. of dioxane was heated at reflux for 24 hours. The reaction mixture was concentrated to remove the solvent. The residue was dissolved in dilute sodium hydroxide and then acidified with hydrochloric acid. The resulting product (13.6 g., m.p. 130° C.) was recrystallized from acetonitrile to give 3-nitro-5-(3,6,9-trioxadecanamido)benzoic acid as a beige solid, m.p. 136°-137° C.
