Procedure

2-(1-Methylethyl)aniline (2.00 g, 14.81 mmol) was added to a solution of 12 mL of phosphoric acid (85%) and 8 mL of nitric acid (65%) at −6° C., followed by sodium nitrite (1.23 g, 17.78 mmol) in 4 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 (4.35 g, 44.43 mmol) and acetylacetone (1.92 g, 19.25 mmol) in 80 mL of ethanol and 20 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 (0.98 g, 27% yield): 1H NMR (400 MHz, CDCl3): δ ppm 1.34 (6H, d, J=6.8 Hz), 2.52 (3H, s), 2.63 (3H, s), 3.12-3.21 (1H, m), 7.19-7.23 (1H, m), 7.28-7.34 (2H, m), 7.77-8.00 (1H, m), 15.23 (1H, brs).
