Versuchsvorschrift
A solution of 2.0 g (8.1 mmol) 4-Bromo-2-methoxy-6-nitro-phenylamine [Zhou, Q-T., et al. Huaxue Xuebao 1980, 38(5), 507-10] in 50 ml methanol/water (2:1) is hydrogenated in the presence of 200 mg Pt/C (Engelhard 4709) at normal pressure for 3 h. Then the catalyst is filtered off and the filtrate is concentrated in vacuo to afford 1.5 g of the title compound as an oil.
