Procedure

To a solution of 4-morpholin-4-ylaniline (1000 mg, 5.62 mmol) in 10 mL of acetic acid and 2 mL of concentrated hydrochloride solution, sodium nitrite (465 mg, 6.74 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 (2764 mg, 33.71 mmol) and acetylacetone (730 mg, 7.30 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-morpholin-4-ylphenyl)hydrazono]pentane-2,4-dione (900 mg, 55%).
