Versuchsvorschrift
4 G. of 1,2-diamino-4-propargylthiobenzene in 40 ml. aceton is treated with 10 g. of methoxy carbonyl isothiocyanate. The mixture is left overnight at room temperature, stripped under vacuum and the residue triturated with ether. Recrystallization from methanol gives pure 1,2-bis-(3-methoxycarbonyl-2-thioureido)-4-propargylthio-benzene.
