Reaction Steps

N-(4-Nitro-2-(phenylsulfonylamino)phenyl)-N'-phenyl urea was prepared from 4-nitro 2-(phenylsulfonylamino) aniline (82 mg) and phenyl isocyanate (33 mg) by method A. The reaction was cooled and then partitioned between saturated ammonium chloride and 9:1 methylene chloride and methanol. The organic phase was dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography (ethyl acetate/hexanes) to afford desired (30.8 mg, 26%).
