[Object]
A novel method for producing an optically active pyrrolidine compound, which is useful as a production intermediate of a pharmaceutical, and a production intermediate thereof, is provided.
[Means for Solution]
According to the production method of the present invention, a chloro compound that is a key intermediate can be produced efficiently industrially by subjecting a mixture of regioisomers obtained by reacting an optically active epoxy compound substituted with aryl, which is easily available, with an amine compound, to chlorination. Furthermore, an optically active pyrrolidine compound can be produced industrially efficiently with the key intermediate.
