(3-Trifluoromethyl-phenyl)-(5-trifluoromethyl-pyridin-2-yloxy)-acetic acid, 100, prepared as described in Example 4, (0.05 mol) was converted into the acid chloride, using the procedure of Example 6. The acid chloride (0.01 mol) was dissolved in tetrahydrofuran (25 mL) and N,N-dimethylaniline (2 mL) and morpholinoethanol (2 mL) were added. The progress of the reaction was monitored by TLC. When the reaction was complete, water and ether were added. The organic phase was washed with dilute hydrochloric acid, dried and concentrated. The residue was chromatographed to afford the title compound 137.
