Versuchsvorschrift
3-Methoxy-5-nitro-biphenyl (176 mg, 0.77 mmol) are hydrogenated in ethanol (5 ml) using palladium on carbon (10%, 17 mg) at atmospheric pressure for 2h. The catalyst is filtered off and the solvent removed in vacuo. Flash chromatography (silica, eluent ethyl acetate/cyclohexane 1:1) affords the product (139 mg, 91%) as a bown oil. MS: m/e=199 (M+).
