Procedure

Biphenyl-2-amine (500 mg, 2.96 mmol) was added to a solution of 3 mL of phosphoric acid (85%) and 2 mL of nitric acid (65%) at −6° C., followed by sodium nitrite (254 mg, 3.55 mmol) in 1 mL of water dropwise at 0° C., and the mixture was stirred at 0° C. for 30 min. Then, to the reaction mixture was added dropwise a solution of potassium acetate (870 mg, 8.88 mmol) and acetylacetone (385 mg, 3.85 mmol) in 60 mL of ethanol and 32 mL of water. The mixture was stirred at room temperature overnight, filtered, washed with water, EtOH/H2O (1/1) and hexane, and dried to give the title compound (420 mg, 51% yield): 1H NMR (400 MHz, CDCl3): δ ppm 2.51 (3H, s), 2.52 (3H, s), 7.29-7.60 (9H, m), 14.63 (1H, s).
