Versuchsvorschrift

To a solution of methyl 8-(4-nitrobiphenyl-3-ylamino)-8-oxooctanoate (270 mg, 0.70 mmol) and ammonium formate (177 mg, 2.8 mmol) in methanol was added catalytic amount of palladium on carbon (5%). The mixture was heated to reflux under a nitrogen atmosphere overnight and filtered. The filtrate was concentrated and purified by biotage column chromatography to give methyl 8-(4-aminobiphenyl-3-ylamino)-8-oxooctanoate (211 mg)
