A mixture of ethyl 6-(acetylamino)-4′-(benzyloxy)-2′,6′-dimethylbiphenyl-3-carboxylate (809 mg, 1.94 mmol), 10% palladium-carbon (50% water-containing product, 404 mg) and ethanol (10 mL) was stirred overnight under a hydrogen atmosphere at room temperature. The catalyst was filtered off, and the filtrate was concentrated under reduced pressure to give the title compound (544 mg, yield 86%) as colorless crystals.
