Mode opératoire

4-Hydroxypiperidine (5.06 g, 50 mmol) was dissolved in N,N-dimethylformamide (200 mL), potassium carbonate (13.8 g, 100 mmol) and (2-bromoethoxy)benzene (12.9 g, 60 mmol) were added thereto, and the mixture was stirred at 70° C. for 18 hours. The reaction solution was extracted with ethyl acetate and the organic layer was washed with a saturated aqueous solution of sodium chloride, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by flash column chromatography to obtain 1-(2-phenoxyethyl)piperidin-4-ol (8.48 g).
