Reaction Steps
A suspension of 4-phenylpiperidine (3.00 g, 18.6 mmol, 1.00 equiv), 3-bromopropan-1-ol (2.12 mL, 22.3 mmol, 1.20 equiv), potassium carbonate (12.8 g, 93.0 mmol, 5.00 equiv), and potassium iodide (124 mg, 0.74 mmol, 0.04 equiv) in n-butanol (50 mL) and 1,4-dioxane (50 mL) was stirred at reflux under argon for 48 hours. The mixture was cooled to room temperature and concentrated. Water (50 mL) was added and the mixture was extracted with CH2Cl2 (4×100 mL). The combined organic solutions were dried over MgSo4 and concentrated. The residue was crystallized from ethyl acetate to give 3.36 g (82%) of tan solid, which was characterized spectroscopically.
