Procedure: To a solution of 2-(BOC)aminoethanol (3.2 g, 20.0 mmol) in DCM (60 mL) were added TEA (5.6 mL, 40.0 mL) and acetyl chloride (3.36 mL, 30 mmol) at 0° C. After the reaction solution was stirred for 2 h, the solvent was removed, and the residue dissolved in water. The organic material was extracted with EtOAc, and the extracts were washed with 1N HCl, dried over MgSO4, concentrated in vacuo. The residue was purified by column chomatography (eluent: EtOAc/Hex=1/10) to give the title compound (3.2 g, 80%). the solvent was removed the residue dissolved in water The organic material was extracted with EtOAc the extracts were washed with 1N HCl dried over MgSO4 concentrated in vacuo The residue was purified by column chomatography (eluent: EtOAc/Hex=1/10)
