Procedure

To 400 ml of ethanol were added 20.6 g (0.30 mol) of the hydrazine hydrochloride and 63.0 g (0.30 mol) of sodium diethyloxalacetate. This mixture was stirred at room temperature for 2 hours, and then heated with refluxing and stirring for 3 hours. After the ethanol was distilled off, 100 ml of water was added to the residue. The resulting mixture was stirred at room temperature for 1 hour, and the crystals yielded were taken out by filtration and washed with water.
