実験手順

4-(4-Hydroxyphenyl)-5-(4-methoxyphenyl)-2,2-dimethylfuran-3(2H)-one (2.0, 6.5 mmol) was added to a mixture of cesium carbonate (10.5 g, 32.2 mmol) and DMF (50 mL) at RT under an atmosphere of nitrogen. The reaction mixture was stirred at RT for 30 min, upon which 2-(chloromethyl)-5-methylpyridine (1.36 g, 9.6 mmol) was added. The mixture was heated at 80° C. for 4 h (the reaction was monitored by TLC). The reaction mixture allowed to cool, diluted with water and extracted with EtOAc. The combined organics were dried over sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by flash column chromatography using 20% ethyl acetate in n-hexane and silica gel (230-400 mesh), to afford 5-(4-methoxyphenyl)-2,2-dimethyl-4-(4-((5-methylpyridin-2-yl)methoxy)phenyl)furan-3(2H)-one (2.0 g, 76.9%,) as an off-white solid. 1H NMR: 200 MHz, DMSO-d6: δ 8.4 (s, 1H), 7.6 (d, 1H), 7.55 (d, 2H), 7.4 (d, 1H), 7.2 (d, 2H), 7.1 (d, 2H), 7.0 (d, 2H), 5.2 (s, 2H) 3.8 (s, 3H), 2.3 (s, 3H), 1.45 (s, 6H). MS: [M+H]+: m/z=415.2. HPLC: (97.5%, Condition-A).
