Procedure
To a solution of [3-(6-Nitro-pyridin-3-yl)-3-aza-bicyclo[3.1.0]hex-1-yl]-carbamic acid tert-butyl ester (150 mg, 0.468 mmol) in MeOH—CH2Cl2 (3:1) was added Pd/C (24.92 mg, 0.234 mmol). The resulting mixture was stirred under H2 balloon (H2/vacuum exchange three times) at r.t. for 4 h. LCMS showed complete conversion. The reaction mixture was then filtered through a pad of Celite with DCM and concentrated to give a black precipitate. This precipitate was diluted in ethyl acetate followed by filtration. The filtrate was then evaporated to give 120 mg of [3-(6-Amino-pyridin-3-yl)-3-aza-bicyclo[3.1.0]hex-1-yl]-carbamic acid tert-butyl ester in 88% yield. MS (ESI) m/e (M+H+): 291.1
