Procedure

2 G. of 1-acetamido-2-nitro-4-(prop-2-en-1-ylthio)-benzene is treated with 20 ml. methanol and 10 ml. 5N aqueous sodium hydroxide at 20°-25° C for one hour. The mixture is diluted with water and the crude product filtered off. Recrystallization from benzene yields 1-amino-2-nitro-4-(prop-2-en-1-ylthio)benzene. This latter compound in 200 ml. acetone is treated with 4 g. methoxy carbonyl isothiocyanate at room temperatue for several days (i.e., until no starting material is present). The mixture is concentrated and the residue triturated with methanol to yield 1-(3-methoxycarbonyl-2-thioureido)-2-nitro-4-(prop-2-en-1-ylthio)benzene.
