Reaktionsschritte

A solution of 1.12 g (4.04 mmol) 1-bromo-4-methoxy-2,3-dinitro-benzene in 25 ml THF is hydrogenated in the presence of 100 mg Raney-Nickel (B113W Degussa) at normal pressure for 3 h. The catalyst is filtered off and the filtrate is concentrated in vacuo to afford 871 mg of the title compound as a grey crystalline solid.
