Reaction Steps

9.9 g (40 mmol) of 4-nitro-2′[1,1′-biphenyl]-3-ol from step A 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 amount of hydrogen had been absorbed, the catalyst was filtered off, and the solvent was distilled off in a rotary evaporator. This gave 8.1 g of 4-amino-2′-chloro[1,1′-biphenyl]-3-ol.
