Procedure

To methanol (2 ml), 2,2'-[(1,3-dioxo-2-phenylmethylene-1,3-propanediyl)diimino]bisbenzoic acid (500 mg) and 1N.NaOH (2.32 ml) were added, and the mixture was stirred at room temperature for 1 hour. Solvent was removed from the reaction mixture, and the residue was treated with acetone and crystallized to give the title compound (478 mg, 87%) in white solid. m.p. 283° C. (dec.)
