The present invention provides a process for producing a 3-aralkyloxypyrrolidine derivative which is important for production of pharmaceutical products and the like. In the present invention, a N-protected-3-hydroxypyrrolidine is converted into a N-protected-3-aralkyloxypyrrolidine by allowing an aralkyl halide to act in the presence of a base and at least one of a metal halide and a phase-transfer catalyst followed by deprotecting a N-protecting group to convert it to a 3-aralkyloxypyrrolidine derivative and subsequently treating the derivative in a solvent containing a polar solvent, thereby obtaining the 3-aralkyloxypyrrolidine derivative as a crystal. According to the present invention, a 3-aralkyloxypyrrolidine derivative of high purity can be produced conveniently and efficiently on an industrial scale.
