Versuchsvorschrift

To a solution of 3-benzyloxy-1,2-dinitrobenzene (2 g, 0.0073 mol) in 300 ml ethanol Raney-nickel (1 g) was added and the mixture was hydrogenated at room temperature and atmospheric pressure until the uptake of hydrogen ceased (30 min). The colourless solution was filtered (celite) and evaporated to dryness in vacuo to give the title compound as an unstable oil (1.6 g) which was used immediately for the next step.
