Versuchsvorschrift

1.6 G. 1,2-diamino-4-phenylthiobenzene is dissolved in 30 ml. acetone and treated with 4 g. methoxycarbonyl isothiocyanate at room temperature overnight. The mixture is concentrated under vacuum and the residue triturated with ether. Recrystallization from methanol-chloroform yields pure 1,2-bis-(3-methoxycarbonyl-2-thioureido)-4-phenylthiobenzene.
