実験手順

A solution of 2 g of 4-(4-chloro-benzylidene)-piperidine-1-carboxylic acid tert-butyl ester and 0.5 g of 5% platinum on carbon in 10 mL of ethanol was allowed to stir overnight under 1 atm of hydrogen. The catalyst was filtered off and, the solution concentrated to give 2 g of 4-(4-chloro-benzyl)-piperidine-1-carboxylic acid tert-butyl ester as an oil.
