| Use | for organic synthesis. is an acetylated derivative of P-aminobenzoic acid and a metabolite of the anesthetic benzocaine. |
| production method | Method 1: p-aminobenzoic acid is used as a starting material and is obtained by acetylation. P-aminobenzoic acid was dissolved in ethyl acetate, acetic anhydride was added with stirring and the temperature was raised to 70 °c. Then it was cooled, filtered, washed twice with water, and then crystallized with ethanol to obtain a finished product. Method 2: with P-toluidine as raw material, it was obtained by acetylation and oxidation. Acetylated with acetic anhydride as raw material, oxidation with potassium permanganate, oxidation temperature of 60-70 deg C. |
