실험 절차
A mixture of ethyl-4-oxo-3-H-phthalazin-1-ylacetate (23.42 g), ethanol (200 ml) and aqueous formaldehyde (37% concentration, 100 ml) was refluxed for 40 hours. This solution was concentrated to 100 ml and was then poured onto ice water (750 ml). The precipitated solid was collected and air-dried (yield: 17.1 g; m.p. 113°-114° C.).
