Reaction Steps

A solution of [2-nitro-5-(3-nitro-phenylamino)-phenyl]-acetic acid (0.49 g, 1.5 mmol) in EtOH (20 ml) is refluxed in the presence of 0.2 ml concentrated H2SO4 for 3 hours before it is concentrated. To the residue is added saturated NaHCO3. The mixture is extracted with ethyl acetate (30 ml×3). The organic layers are combined and dried with Na2SO4 to give [2-nitro-5-(3-nitro-phenylamino)-phenyl]-acetic acid ethyl ester: LC-MS: 346.0 (MH+).
