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

Participants

Reaction Steps

1-Acetyl-2-[4-(4-methoxybenzyl)aminophenyl]hydrazine (3.1 g, 0.011 mole) and phenylisothiocyanate (1.35 g, 0.01 mole) were mixed in ethanol (25 ml) and the resulting mixture was refluxed for 10 minutes. The mixture was chilled in ice and diluted with water. The product oiled out of solution, but upon standing and scratching the substance solidified. The solid material was filtered off, washed with water and allowed to dry. The material was stirred twice in a large volume of ether, then was filtered and washed with fresh ether. The product was a white powder. Yield 2.75 g (66%), m.p. 126°-128° C.
