Procedure
To a stirred solution of glutamic acid (10 mmol) and sodium carbonate (10.5 mmol) in water (50 mL) is added ethyl 4-nitro-1,3-dioxoisoindoline-2-carboxylate (10 mmol). The resulting mixture is stirred for 3 hours. The mixture is filtered. The filtrate is then acidified to pH 1 with 4 N hydrochloric acid to afford the 1-(4-nitro-1,3-dioxoisoindolin-2-yl)propane-1,3-dicarboxylic acid.
