実験手順

A mixture of afford tert-butyl 2-azidopropylcarbamate (7.0 g, 3.6 mmol) and Pd/C (0.7 g) in MeOH (250 mL) was stirred under a H2 (1 atm) atmosphere (RT, 16 h). The mixture was filtered and concentrated under reduced pressure. The crude product was purified by chromatography on silica gel, eluting with saturated NH3 in MeOH-DCM (0-10%) to afford tert-butyl 2-aminopropylcarbamate (5.1 g, 83.7%) as a light yellow oil. 1HNMR (CDCl3): δ 4.9 (bs, 1H, NH), 3.15 (m, 1H, CH), 3.0 (m, 1H, CH2), 2.8 (m, 1H, CH2), 1.7 (bs, 2H, NH2), 1.5 (s, 9H, CH3), 1.0 (d, 3H, CH3).
