Procedure

The procedure of Example 4 was repeated to react 2-(4-carboxybenzamido)-4-aminobenzoic acid with propionyl chloride, and the reaction product was treated as in Example 4 except that isopropyl alcohol was used as a solvent for recrystallization. The product obtained was a 62% yield of 2-(4-carboxybenzamido)-4-propionamidobenzoic acid having a melting point in the range of from 284° to 286° C. (decompose).
