Versuchsvorschrift

Diethyl 2-[6-methoxy-4-(2-methyl-quinolin-3-yloxy)-quinolin-7-yloxy]-malonate (compound 373) (50 mg) was dissolved in tetrahydrofuran (1 ml) to prepare a solution. Lithium aluminum hydride (10 mg) was added to the solution at 0° C., and the mixture was stirred at 0° C. for 3 hr and then at room temperature for 2 hr. Water was added to the reaction solution to stop the reaction. The mixture was filtered through Celite, water was then added to the filtrate, and the mixture was extracted with chloroform. The chloroform layer was washed with water and was then dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by thin layer chromatography using chloroform-methanol to give the title compound (9.1 mg, yield 22%).
