Procedure

To a mixture of 4-amino-1-benzylpiperidine (2.13 g, 11.2 mmol) and 2-bromoethanol (0.15 g, 4.08 mmol) in anhydrous CH2Cl2 (20 ml) was added Hunig's base (2.6 ml, 5.7 mmol). The solution was refluxed for 24 hours. After evaporating off CH2Cl2, the crude material was purified by silica flash chromatography to afford 2-[[1-(phenylmethyl)-4-piperidinyl]amino]ethanol (0.88 g, 3.8 mmol) with 92% yield. FAB Mass [M+1]+35Cl 235.
