実験手順
By the procedure similar to that described in Example 23, 2-(2'-acetoxybenzamido)-4-aminobenzoic acid and 2-acetoxybenzoylchloride were allowed to react and were treated to obtain crude crystals. Recrystallization from methanol-water gave 2,4-bis(2'-acetoxybenzamido)-benzoic acid having a melting point between 194° - 195°C. The product wass confirmed to be identical to that obtained in Example 18.
