Procedure

4-[2-(4,5-Dimethyl-thiazol-2-yl)-5,6-dimethyl-pyridin-3-yloxy]-6-methoxy-quinolin-7-ol (compound 455) (41 mg) was suspended in N,N-dimethylformamide (2 ml). Potassium carbonate (42 mg) and epibromohydrin (0.03 ml) were added to the supension, and the mixture was stirred at room temperature overnight. The solvent was removed by distillation under the reduced pressure, water was then added to the residue, 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-methanol to give the title compound (44 mg, yield 94%).
