Into a NaOH aqueous solution (2.30 g, 24.0 mL) for hydrolysis, 6.24 g (48.0 mmol) of ethyl acetoacetate was added, and stirred under heating at 30° C. for 3 hours. After the three hours, the reaction mixture was cooled down to 0° C., and a 5 N HNO3 aqueous solution was added thereto to make the reaction liquid acidic. To the reaction mixture, 2.90 g (4.80 mmol) of a copper (II) nitrate aqueous solution was added dropwise, and subjected to magnetic stirring for 4 hours. The precipitated solid was taken out by filtration, and washed with ion-exchanged water and acetone to obtain 2.05 g (6.70 mmol) of copper (II) acetoacetate dihydrate in the form of light blue solid.
