Versuchsvorschrift

Under argon, 3-trifluoromethylphenyl 4-hydroxyphenyl ketone (432 mg) obtained in Example 139 and 4-chloro-6,7-dimethoxyquinoline (363 mg) were dissolved in diethylene glycol dimethyl ether (10 ml), and the solution was then refluxed at 160° C. for 11 hours. The reaction mixture was partitioned between saturated aqueous sodium hydrogen carbonate and chloroform, and the chloroform layer was dried with anhydrous magnesium sulfate. After removing the solvent by reduced-pressure distillation, the resulting residue was purified by chromatography on silica gel eluting with hexane/ethyl acetate and then by thin layer chromatography on silica gel eluting with chloroform/ethyl acetate (5/1) to obtain 204 mg of the title compound (yield: 28%).
