2′-Methoxy-3′-nitro-biphenyl-3-carboxylic acid 1d (0.48 g, 1.74 mmol) was dissolved in 60 mL of ethanol followed by addition of 0.5 g of palladium on carbon (10%) and ammonium formate (1.1 g, 17.4 mmol). The reaction mixture was heated to reflux at 80° C. for 20 minutes. The mixture was filtered and the filtrate was concentrated under reduced pressure and dried to obtain the title compound 2′-methoxy-3′-amino-biphenyl-3-carboxylic acid 1e (0.42 g, yield 93.3%) as a white solid.
