2.1 G. 1,2-diamino-4-phenylsulfinylbenzene in 150 ml. acetone is treated with 6 g. methoxy carbonyl isothiocyanate overnight at 20°-25° C. The reaction mixture is stripped and the residue triturated with ether. Recrystallization from methanol yields pure 1,2-bis-(3-methoxycarbonyl-2-thioureido)- 4-phenylsulfinylbenzene.
