The procedure of Example 1 was repeated for reacting 7-(propionamido)-2-(4-carboxyphenyl)-4H-3,1-benzoxazine-4-one with n-propanol, and the reaction product was treated as in Example 1 except that the solvent for recrystallization was a mixture of dioxane and water. The product obtained was a 80% yield of propyl 2-(4-carboxybenzamido)-4-propionamidobenzoate having a melting point in the range of from 233° to 235° C.
