Versuchsvorschrift

[3-(6,7-Dimethoxy-quinolin-4-yloxy)-6-methyl-pyridin-2-yl]-(6-methyl-pyridin-2-yl)-methanol (43 mg) was dissolved in chloroform (6 ml) to prepare a solution. Triethylamine (0.9 ml) and acetic anhydride (0.45 ml) were added to the solution, and the mixture was stirred at room temperature overnight. Water was added to the reaction solution, and the mixture was extracted with chloroform. The chloroform layer was washed with saturated brine and was 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-acetone to give the title compound (28 mg, yield 61%).
