Potassium Carbonate → 1-[3-(4-Benzyloxy-phenyl)-isoxazol-5-ylmethyl]-piperidin-4-ol

Participants

Reaction Steps

Methanesulfonic acid-3-(4-benzyloxy-phenyl)-isoxazol-5-ylmethyl ester (150 mg, 0.42 mmol), 4-hydroxypiperidine (64 mg, 0.63 mmol), potassium carbonate (87 mg, 0.63 mmol), and TBAI (96 mg, 0.26 mmol) were placed in 10 ml of DMF and stirred at room temperature overnight. 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 recrystallized from methylene chloride:MeOH (9:1) to obtain 1-[3-(4-benzyloxy-phenyl)-isoxazol-5-ylmethyl]-piperidin-4-ol as a white solid compound.
