1-(4-Chlorobenzoyl)-2-(4-aminophenyl)hydrazine hydrochloride (2.0 g, 0.0067 mole) was mixed with ethanol (125 ml) and water (25ml). Phenyl isothiocyanate (1.1 g, 0.01 mole) was added to the mixture along with sodium acetate (0.82 g, 0.1 mole) in water (10 ml). The reaction mixture was stirred and refluxed for 5 minutes, then was stirred at room temperature for 11/2 hours. The mixture was chilled in ice and then filtered. The product was washed with ethanol and dried to give an off-white solid. Yield 1.9 g (71%), m.p. 197.5°-199° C.
