Imidazole → 3-(4-Benzyloxy-phenyl)-5-imidazol-1-ylmethyl-isoxazole

Participants

Reaction Steps

Methanesulfonic acid-3-(4-benzyloxy-phenyl)-isoxazol-5-ylmethyl ester (600 mg, 1.67 mmol), imidazole (170 mg, 2.50 mmol), potassium carbonate (460 mg, 3.34 mmol), and TBAI (200 mg, 0.54 mmol) were placed in 20 ml of DMF and stirred for 2 hours. The completion of the reaction was confirmed by LC, and then a crude solid compound obtained from distillation of the DMF under reduced pressure was extracted with ethyl acetate and water. The ethyl acetate 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-benzyloxy-phenyl)-5-imidazol-1-ylmethyl-isoxazole as a white solid compound.
