Process for producing high-purity 1-benzyl-3-aminopyrrolidine

An industrially practicable purification method is provided by which 1-benzyl-3-aminopyrrolidine having a high chemical purity can be produced in a high yield. A salt is formed from tartaric acid and low-chemical-purity 1-benzyl-3-aminopyrrolidine containing impurities. The salt is crystallized from a mixed solvent comprising water and an organic solvent miscible with water to thereby produce high-purity 1-benzyl-3-aminopyrrolidine.
