2.6 G. of 2-nitro-4-phenylsulfinylaniline is dissolved in 25ml. of acetone and treated at 20°-25° C with 60 ml. of a solution of methoxycarbonyl isothiocyanate (made from 0.075 mol. (each) of potassium thiocyanate and methylchloroformate in acetone). After several days, the solvent is evaporated and the residue triturated with ether. Recrystallization from methanol-chloroform yields 2-nitro-4-phenylsulfinyl-1-(3-methoxycarbonyl-2-thioureido)benzene.
