Sodium Iodide → 1-[4-(3-Piperidin-1-ylpropoxy)phenyl]ethanone

참여 물질

반응 단계

A mixture of 5.97 g of 4′-hydroxyacetophenone (43.8 mmol), 13.0 g of 1-(3-chloropropyl)-piperidine hydrochloride (65.8 mmol), 12.70 g of potassium carbonate (91.89 mmol), and 3.28 g of sodium iodide (21.9 mmol) in 100 mL dry acetone was stirred at reflux. After 1.5 h, the reaction was cooled to room temperature, filtered and concentrated. Ethyl acetate was added and the white solid that remained was filtered off. The filtrate was concentrated in vacuo and the crude residue was purified via silica gel chromatography using a gradient of ethyl acetate then 400:20:10 ethyl acetate: 7N ammonia in methanol:methanol to yield 583 mg of 1-[4-(3-piperidin-1-ylpropoxy)phenyl]ethanone as an oil. MS m/z 265 (M+H).
