Versuchsvorschrift

A mixture of 210 mg 4-(6-methoxypyridin-3-yl)-6-(3-trifluoromethyl-1-trityl-1H-pyrazol-4-yl) quinoline obtained in Example 1063 and 10 mL trifluoroacetic acid was stirred at room temperature for 1 hour. The trifluoroacetic acid was evaporated, and an aqueous saturated sodiumbicarbonate solution was added to the residue which was then extracted with ethyl acetate. The organic layer was washed with brine and dried over anhydrous magnesium sulfate. The solvent was evaporated, and the residue was purified by silica gel column chromatography to give 110 mg of the title compound as a colorless solid.
