実験手順
5-(2-Chloro-4-trifluoromethylphenoxy)-2-nitrobenzoic acid (3.0 g, 0.0083 mole) is dissolved in glyme (20 ml) and dicyclohexylamine (1.64 g, 0.0091 mole) is added at room temperature while stirring. The solvent is removed in vacuo, the residue triturated with petroleum ether (bp 30°-60° C.) and dried to give 2.7 g of product, mp 197°-9° C.
