Reaction Steps

To a solution of 4-(trifluoromethyl)aniline (1090 mg, 6.80 mmol) in 5 mL of water and 5 mL of concentrated hydrochloride solution, sodium nitrite (563 mg, 8.16 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 (1670 mg, 20.40 mmol) and acetylacetone (748 mg, 7.48 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-(trifluoromethyl)phenyl]hydrazono}pentane-2,4-dione (580 mg, 31%).
