Reaction Steps

To a solution of 4-methylaniline (1000 mg, 9.34 mmol) in 10 mL of acetic acid and 2 mL of concentrated hydrochloride solution, sodium nitrite (774 mg, 11.21 mmol) in 4 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 (2299 mg, 28.04 mmol) and acetylacetone (1215 mg, 12.15 mmol) in 10 mL of ethanol and 6 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-[(4-methylphenyl)hydrazono]pentane-2,4-dione (480 mg, 24%).
