Versuchsvorschrift
Benzyl (1S,2S,4R)-4-(tert-butyldimethylsilyloxy)-2-(prop-1-en-2-yl)cyclohexylcarbamate (4.8 g) in MeOH (40 mL) was charged with 10% Pd/C, Degussa (600 mg). The reaction flask was evacuated and then back-filled with hydrogen; this was repeated three more times. The reaction was stirred under 1 atm of H2 for 4 h and then filtered and concentrated to provide (1S,2S,4R)-4-(tert-butyldimethylsilyloxy)-2-isopropylcyclohexanamine (2.9 g). MS (ES+)=272.3 (M+H)+.
