実験手順

3-(3,4-Dichloro-benzylidene)-8-aza-bicyclo[3.2.1]octane-8-carboxylic acid tert-butyl ester (1.0 g, 2.7 mmol) in 10 mL of EtOH and 10 mL of EtOAc was stirred with 25 mg of PtO2 under 1 atm of H2 at rt for 3 h. It was then filtered through a celite bed and the filtrate was concentrated. The residue was purified on a silica gel column to give 0.84 g of 3-(3,4-dichloro-benzyl)-8-aza-bicyclo[3.2.1]octane-8-carboxylic acid tert-butyl ester (M++1: 370).
