実験手順
To a solution of 5-(3,4-dichloro-benzyl)-2-aza-bicyclo[2.2.2]octane-2-carboxylic acid tert-butyl ester (0.24 g, 0.65 mmol) in 2 mL of CH2 Cl2 was added 1 mL of TFA. After the mixture was stirred at rt for 1 h, it was quenched with NaHCO3 (sat.). It was then extracted with CH2Cl2 and the organic layer was washed with NaCl (sat.), dried over Na2SO4 and concentrated to give 170 mg of 5-(3,4-Dichloro-benzyl)-2-aza-bicyclo[2.2.2]octane (M++1: 270).
