実験手順
3′-Aminobiphenyl-4-carboxylic acid (0.2 g) was mixed with pyridine (0.7 g) and acetic anhydride (180 mg) and, after 14 hours, volatile fractions were removed. The residue was taken up in sodium hydroxide solution (2N) and washed with diethyl ether. The aqueous phase was acidified with hydrochloric acid and extracted with ethyl acetate. The organic phase was dried over magnesium sulfate and concentrated. This resulted in the product with the molecular weight of 255.28 (C15H13NO3); MS (ESI): 256 (M+H+).
