반응 단계
A mixture of 4-[(5-chloro-2-pyridinyl)methoxy]-1-(4-hydroxyphenyl)-1H-pyridin-2-one (1.0 g, 3.1 mmols), cesium carbonate (5.0 g, 15 mmols), dibromoethane (5 mL) and DMF (10 mL) was stirred at 80° C. for 14.5 hours. Chloroform was added to the reaction liquid, followed by filtration. Concentrating the solvent under reduced pressure, the residue was purified on silica gel column chromatography (KP-Sil FLASH 25+ M, chloroform:methanol=1:0→100:2) to provide the title compound (1.2 g, 89%).
