Versuchsvorschrift

8.8 g (40 mmol) of 4-nitro-1,1′-biphenyl-3-ol from step B was dissolved in 120 mL of ethanol and hydrogenated in the presence of 0.8 g of a palladium-activated carbon catalyst (10%) at 25° C. After the required quantity of hydrogen had been absorbed, the catalyst was filtered off, and the solvent was distilled off in a rotary evaporator. This gave 7.3 g of 4° amino-1,1′-biphenyl-3-ol.
