Procedure

A solution of 564 mg (1.5 mmol) of 4,5-bis(anilino)phthalic acid dimethyl ester (Example 1) in 5 ml of acetonitrile is heated at 80° C. for 16 hours with 0.93 ml (15 mmol) of methyl iodide and 442 mg (3.2 mmol) of anhydrous potassium carbonate in a bomb tube. The reaction mixture is concentrated to dryness by evaporation, the residue is twice digested in dichloromethane and filtered, and the filtrate is concentrated by evaporation. Repeated chromatography on silica gel with hexane/ethyl acetate yields the title compounds in the form of slightly yellowish powders. (A): FAB-MS: 405 [M+ +H]; (B): FAB-MS: 391 [M+ +H].
