PROBLEM TO BE SOLVED: To provide a method for simply and industrially producing a chemokine receptor antagonist.
SOLUTION: The present invention relates to a method for producing aminopyrrolidine derivatives represented by formulas (wherein R11is hydrogen atom, a 1-6C alkyl group or a 2-7C alkanoyl group; R12, R14, R15, R16and R17are each independently hydrogen atom, a halogen atom, a 1-6C alkyl group which is substituted with a halogen atom, a 1-6C alkoxyl group which is substituted with a halogen atom, a hydroxy group or a 2-7C alkoxycarbonyl group; R1and R2are each independently hydrogen atom or a protective group of an amino group in which R1 and R2 together may form a ring structure; R23, R24, R25and R26are each independently hydrogen atom, a halogen atom, a 1-6C alkyl group which may be substituted with a halogen atom, a 1-6C alkoxyl group which may be substituted with a halogen atom or a hydroxy group; R3is a hydrogen atom or a 1-6C alkyl group) or their salts.
