| Zusammenfassung: | The present invention provides a method for producing an optically active 2-methylpiperazine including: adding a solvent to a solution of the optically active 2-methylpiperazine to carry out solvent replacement, and then being crystallized to obtain crystals of the optically active 2-methylpiperazine. The method for producing an optically active 2-methylpiperazine according to the present invention allows the optically active 2-methylpiperazine to be purified during the crystallization process, and thus it is possible to obtain an optically active 2-methylpiperazine having a high quality. |
