Versuchsvorschrift
2.0 G. of 1-amino-2-nitro-4-thiocyanatobenzene in 20 ml. acetone is treated with 3.0 g. methoxycarbonyl isothiocyanate at room temperature for 9 days. The solution is concentrated and the residue triturated with methanol and recrystallized from acetone, yielding 1-(3-methoxycarbonyl-2-thioureido)- 2-nitro-4-thiocyanatobenzene.
