Phenyl Isothiocyanate → 1-[4-(2-Acetylhydrazino)phenyl]-3-phenylthiourea

Participants

Reaction Steps

1-Acetyl-2-(4-aminophenyl)hydrazine (8.25 g, 0.05 mole) and phenyl isothiocyanate (6.8 g, 0.05 mole) were suspended in acetonitrile (100 ml). The resulting mixture was heated at reflux with stirring for 5 minutes. The product separated from solution as a white solid. After chilling, the product was removed from the reaction mixture by filtration and washed thoroughly with ether. Yield 14.5 g (96%), m.p. 205°-207° C.
