Reaction Steps

6,7-Dimethoxy-4-[6-methyl-2-(1H-pyrazol-4-yl)-pyridin-3-yloxy]-quinoline (compound 434) (30 mg) was suspended in N,N-dimethylformamide (1 ml), 60% sodium hydride (9.9 mg) was added to the suspension, and the mixture was then stirred for 30 min. Methyl iodide (18 mg) was added to the reaction solution, and the mixture was stirred for one hr. Water was added to the reaction solution to stop the reaction, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with water and was then dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure. The residue was purified by thin layer chromatography using hexane-acetone to give the title compound (23 mg, yield 73%).
