Reaction Steps

To a solution of 4-cyclohexylaniline (500 mg, 2.86 mmol) in 10 mL of acetic acid and 2 mL of concentrated hydrochloride solution, sodium nitrite (237 mg, 3.43 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 (703 mg, 8.58 mmol) and acetylacetone (372 mg, 3.72 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-cyclohexylphenyl)hydrazono]pentane-2,4-dione (420 mg, 51%).
