Versuchsvorschrift

A solution of 5 mmol of 2-(4-((6-fluoro-2-quinolinyl)oxy)phenoxy)propionyl chloride in 5 milliliters (ml) of methylene chloride was slowly added to an ice-cooled solution comprising 1.17 grams (g) (5.5 mmol) of 4-(trifluoromethoxy)aniline hydrochloride and 1.21 g (12 mmol) of triethylamine in 40 ml of methylene chloride. The reaction mixture was stirred at 0° C. for 30 minutes then at room temperature for 3 hours. The mixture was poured into a dilute aqueous HCl solution. The organic layer was separated, washed with water, then washed with a saturated aqueous NaHCO3 solution, dried over MgSO4 and evaporated to dryness. The residual solid was taken up in methylene chloride and filtered through a short column of silica gel, eluting with additional methylene chloride. After removal of the solvent, the residue was recrystallized from methylcyclohexane to give 1.0 g (41 percent of theoretical) of the above-named product as colorless crystals. The product melted at 134°-136° C. and its structure was confirmed by its infrared (IR) and its nuclear magnetic resonance (NMR) spectrum. (Compound 3)
