Synthesis of 6-carbomethoxy-3-Phenyl-5-(4-dimethylaminophenyl)-cyclohexenone

A mixture of 4-dimethylaminochalcone 1 (0.25 g, 1.00 mmol), methyl acetoacetate (0.17 g, 1.5 mmol) in methanol (5.00 mL) and sodium metoxide (0.25 mg) was stirred at room temperature for 24 hour to give a yellow precipitate. Then it was filtered and washed with water. Recrystalized of the crude substance from methanol afforded pure cyclohexenone 2 (2.27 g, 97.00 %). © 2005 MDPI. All rights reserved.
