반응 단계

To a stirred solution of 2-(1-trityl-1H-imidazol-4-yl)phenol (0.5 mmol) in anhydrous DMF (3 mL) at 0° C. was added NaH (36.0 mg, 0.75 mmol). The resulting suspension was allowed to stir for 10 min. To the resulting solution was added 1-(benzofuran-3-yl)-2-bromoethanone (0.50 mmol). After stirring overnight, the reaction mixture was carefully diluted, with water and extracted with ethyl acetate (2×10 mL). The combined organic layers were washed with water, brine and dried (Na2SO4). The solvent was removed under reduced pressure and the crude product was purified by column chromatography. Yield 60%. 1H NMR: 5.16 (s, 2H), 6.88 (d, 1H, J=8.10 Hz), 7.06-7.47 (m, 20H), 7.54 (d, 2H, J=7.92 Hz), 8.22 (dd, 2H, J=7.60 Hz, 1.35 Hz), 8.33 (s, 1H).
