Versuchsvorschrift

1.5 G. of 1,2-diamino-4-n-butylthiobenzene in 30 ml. acetone is treated overnight with 4.5 g. methoxy carbonyl isothiocyanate at room temperature. The solution is concentrated, and the residue triturated with methanol and recrystallized from methanol, yielding 1,2-bis-(3-methoxycarbonyl-2-thioureido)-4-n-butylthiobenzene.
