실험 절차

1-Formyl-2-(4-aminophenyl)hydrazine (30 g, 0.20 mole) was dissolved in acetonitrile (550 ml) with heat. Phenyl isothiocyanate (28 g, 0.22 mole) was added in one portion. The mixture was refluxed for 5 minutes and then chilled. The solid was filtered off, washed with acetonitrile and dried at 75° C. Yield 52 g (91%), m.p. 188°-188.5° C.
