| titleOfInvention | Preparation method of N-p-aminobenzoyl glutamyl folic acid |
| abstract | The invention belongs to the field of organic synthesis, and particularly relates to a preparation method of N-p-aminobenzoyl glutamyl folic acid, which comprises the following steps: folic acid and p-aminobenzoyl glutamic acid are used as raw materials, organic alkali is added into an organic solvent, under the action of a condensing agent, a condensation activating agent and a catalyst, a crude product of N-p-aminobenzoyl glutamyl folic acid is generated through condensation reaction, and the N-p-aminobenzoyl glutamyl folic acid is obtained through preparative chromatographic separation. The invention provides a preparation method of N-p-aminobenzoyl glutamyl folic acid, which is used for the quality control of folic acid and is beneficial to further research on the generation mechanism and the control method of the N-p-aminobenzoyl glutamyl folic acid. |
