The (4-methoxyphenyl)malonaldehyde (1.5 g, 8.42 mmol) was dissolved in ethanol (10 mL), followed by addition of hydrazine (540 mg g, 16.8 mmol). The pale yellow solution was heated in a microwave sealed tube at 110° C. overnight. Large amount of white crystalline solid formed. The reaction mixture was cooled to 0° C. The white solid was collected by filtration and was washed with 5 mL of ice-cold ethanol to give the desired product, which was further dried under high vacuum pump.
