Reaction Conditions

Reaction Steps

To piperidin-4-ol (HCl salt, 9.0 g) was added a solution of benzyl 2-bromoacetate (15.0 g, 65.7 mmol) in dichloromethane (100 mL). The mixture was cooled to 0° C. and triethylamine (27.6 mL, 0.200 mol) was added. The reaction mixture was allowed to warm to ambient temperature and stirred for 2 h. Water (100 mL) was added and the resulting mixture was extracted with dichloromethane (100 mL×3). The organic extracts were combined, dried over anhydrous sodium sulfate, and concentrated. The residue was purified by flash column chromatography on silica gel (dichloromethane/methanol=20:1 to 10:1) to afford benzyl 2-(4-hydroxypiperidin-1-yl)acetate (8.3 g, 51% yield).
