(1S,3S,5S)-3-(b enzylamino-methyl)-2-aza-bicyclo[3.1.0]hexane-2-carboxylic acid tert-butyl ester → (1S,3S,5S)-tert-Butyl 3-(aminomethyl)-2-azabicyclo[3.1.0]hexane-2-carboxylate

Participants

Reaction Steps

A solution of (1S,3S,5S)-3-(b enzylamino-methyl)-2-aza-bicyclo[3.1.0]hexane-2-carboxylic acid tert-butyl ester (16.7 mmol) in EtOH (100 mL) is treated with Pd/C (2.0 g, 50% H2O) and stirred under a hydrogen atmosphere (1 bar) for 1 d. An additional amount of Pd/C (2.0 g) is added and the mixture is stirred for further 3 d. After filtration through celite and removal of the solvents the desired amine is obtained which is used without further purification. LC-MS (acidic): tR=0.64 min; [M+H]+=213.3.
