Reaction Steps

To a solution of 4-fluoroaniline (1000 mg, 9.00 mmol) in 10 mL of acetic acid and 2 mL of concentrated hydrochloride solution, sodium nitrite (746 mg, 10.80 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 (2220 mg, 27.00 mmol) and acetylacetone (990 mg, 9.90 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-fluorophenyl)hydrazono]pentane-2,4-dione (1200 mg, 60%).
