The present invention provides a process for producing optically active 3-hydroxy-4-methoxypyrrolidine, which is an intermediate for synthesizing a quinuclidine derivative useful as a squalene synthetase inhibitor, a salt thereof, or a hydrate thereof by subjecting a pyrrolidine derivative represented by the following formula (1-4):
1
wherein R
3a
and R
3b
are different and each of R
3a
and R
3b
represents a hydrogen atom or a methyl group, to optical division purification by using an optically active dibenzoyltartaric acid derivative or the like.
