METHOD FOR PRODUCING ACETAMIDOPYRROLIDINE DERIVATIVE AND INTERMEDIATE COMPOUND THEREOF

摘要

Disclosed is a method for producing an acetamidopyrrolidine derivative or a salt thereof comprising a reaction process expressed by the following formulae. Formulae In the formulae, R<1> represents a hydrogen atom or a C1-C6 alkyl group; R<13>, R<14>, R<15> and R<16> independently represent a hydrogen atom, a halogen atom, a C1-C6 alkyl group, a C1-C6 alkoxy group, a hydroxy group, a C1-C6 halogenated alkyl group or a C1-C6 halogenated alkoxy group; and R<21> represents an ester-protecting group.
