실험 절차

1-(4-chlorobenzoyl)-4-ethylsemicarbazide (23.7 g, 9.81×10-2 mole) and 1 molar aqueous NaOH (118 ml, 1.18×10-1 mole) were stirred and warmed to reflux. After refluxing 23 hours, heating was discontinued and the reaction was acidified by the dropwise addition of 1 molar aqueous hydrochloric acid (130 ml, 1.30×10-1 mole). A colorless solid formed as the reaction was acidified and, after cooling in an ice bath, this was collected by filtration. Crystallization from isopropanol gave colorless spars: 18.2 g (83%), mp 188°-189°.
