실험 절차

4-(5-imidazol-1-ylmethyl-isoxazol-3-yl)-phenol (150 mg, 0.62 mmol) and potassium carbonate (172 mg, 1.25 mmol) were placed in 10 ml of DMF, to which solution was added dropwise 3-fluorobenzyl bromide (89 μl, 0.75 mmol), and the mixture was stirred at room temperature for 4 hours. The completion of the reaction was confirmed by LC, and then DMF was distilled off under reduced pressure. A crude solid compound was extracted with ethyl acetate and water, and the organic solvent was distilled off under reduced pressure to obtain a white solid compound. The compound was purified by silica chromatography (methylene chloride:MeOH=20:1) to obtain 3-[4-(3-fluoro-benzyloxy)-phenyl]-5-imidazol-1-ylmethyl-isoxazole as a desired white solid compound.
