Versuchsvorschrift

5-(2-Chloro-4-trifluoromethylphenoxy)-2-nitrobenzoic acid (3.0 g, 0.0083 mole) is dissolved in glyme (20 ml) and a solution of triethanolamine (1.35 g, 0.0091 mole) in glyme (5 ml) is added rapidly while stirring at room temperature. After stirring for a few hours the solvent is removed in vacuo, the product is triturated repeatedly with petroleum ether (bp 30°-60° C.) and dried to a weight of 2.5 g. Anal. Calcd. for C20H22ClF3N2O8 : C, 47.02; H, 4.34; Cl, 6.39; N, 5.48; F, 11.15. Found: C, 47.08; H, 4.78; Cl, 6.48; N, 5.21; F, 10.16.
