摘要:
Disclosed is a process for production of an aralkyloxypyrrolidine derivative which is important for the production of a pharmaceutical or the like. A 3-aralkyloxypyrrolidine derivative can be produced in the form of a crystal by a process comprising reacting an N-protected-3-hydroxypyrrolidine with a halogenated aralkyl in the presence of a base and a metal halide and/or a phase transfer catalyst to give an N-protected-3-aralkyloxypyrrolidine, performing the deprotection of the N-protecting group in the product to give a 3-aralkyloxypyrrolidine derivative, and treating the product in a solvent containing a polar solvent. The process can produce a highly pure 3-aralkyloxypyrrolidine derivative in a simple manner, with good efficiency, and in an industrial scale.
