Procedure
By the procedure similar to that described in Example 23, 2-(2'-methoxybenzamido)-4-aminobenzoic acid and 2-methoxybenzoylchloride were reacted and treated to obtain crude crystals. Recrystallization from aqueous alcohol gave 2,4-bis(2'-methoxybenzamido)-benzoic acid having a melting point between 232° - 233°C which was identical to that obtained in Example 10.
