Versuchsvorschrift

To a solution of tert-butyl ethyl(3-(5-nitro-1H-indol-3-yl)cyclohexyl)carbamate (0.24 g, 0.62 mmol) in dry MeOH (10 mL) was added Raney-Ni (0.1 g as a slurry in water) and hydrazine hydrate (0.30 mL, 6.20 mmol). The resulting mixture was immersed in a preheated oil bath and refluxed for 15 min. or until the solution became clear. The reaction was cooled and filtered trough celite, washed with MeOH (20 mL) and the solvent evaporated. The crude material was purified on column chromatography (2 M NH3 in MeOH:CH2Cl2, 2:98) to give the title compound as a brownish solid (0.21 g, 96%). 1H-NMR (CDCl3) δ1.09 (t, 3H, J=6.9 Hz), 1.30-1.66 (m, 3H), 1.48 (s, 9H), 1.80-1.83 (m, 1H), 1.90-1.94 (m, 1H), 1.98-2.04 (m, 1H), 2.11-2.15 (m, 1H), 2.80-2.90 (m, 1H), 3.05-3.22 (m, 2H), 4.12-4.19 (m, 1H), 6.65 (dd, 1H, J=2.1, 8.7 Hz), 6.87 (d, 1H, J=2.1 Hz), 6.96 (s, 1H), 7.15 (d, 1H, J=8.7 Hz), 7.725 (s, 1H); EI-MS (m/z, %) 357 (M+, 100).
