실험 절차
3-(3,4-Dichloro-benzyl)-8-aza-bicyclo[3.2.1]octane-8-carboxylic acid tert-butyl ester (0.35 g, 0.94 mmol) was stirred in 2 mL of CH2Cl2 with 0.5 mL of TFA at rt for 3 h. After being quenched with 20% NaOH to basic medium, the mixture was extracted with EtOAc. The organic layer was washed with NaCl (sat.), dried over Na2SO4 and concentrated to give 0.25 g of 3-(3,4-Dichloro-benzyl)-8-aza-bicyclo[3.2.1]octane.
