Versuchsvorschrift

To a solution of 50 mg (0.077 mmol) of (−)-4-(4,4-Difluorocyclohexyl)-3-{fluoro[4-(trifluoromethyl)phenyl]methyl}-2-[1-(5-hydroxypyrimidin-2-yl)piperidin-4-yl]-7,7-dimethyl-5,6,7,8-tetrahydroquinolin-5-ol, which was prepared by a method similar to that of Example 4, in 1.0 ml of N,N-dimethylformamide, 75 mg (0.23 mmol) of cesium carbonate and 12 μl (0.15 mmol) of ethyl iodide were added, and the reaction solution was stirred at room temperature for 1 hour. After completion of the reaction, the reaction solution was poured into water and extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride aqueous solution and dried with anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. The obtained residue was purified by preparative thin layer chromatography [n-hexane/ethyl acetate=70/30 (V/V)] to provide 45 mg of the title compound as a white solid (yield: 85%).
