摘要：
An object of the present invention is to provide an optically active bicyclic γ-amino acid derivative in a high purity. The object can be attained by a mixture of compounds represented by the general formulas (I) and (I'), or a method for producing a compound represented by the general formula (VII) or a salt thereof via the compound (I):
wherein R 1 and R 2 each represent a C1-6 alkyl group or the like; and R 3 represents a cyano group or the like,
wherein R 1 and R 2 each represent a C1-6 alkyl group or the like; and R 3 represents a cyano group or the like,
