Reaction Steps

To a solution of aniline (2000 mg, 21.50 mmol) in 30 mL of acetic acid and 5 mL of concentrated hydrochloride solution, sodium nitrite (1780 mg, 25.80 mmol) in 8 mL of water was added dropwise at 0° C., and the mixture was stirred at 0° C. for 1 h. Then to the reaction mixture was added dropwise a solution of sodium acetate (5290 mg, 64.50 mmol) and acetylacetone (2795 mg, 27.95 mmol) in 20 mL of ethanol and 12 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 3-(phenylhydrazono)pentane-2,4-dione (2955 mg, 67%).
