PROBLEM TO BE SOLVED: To provide an industrially advantageous method for producing a 2,2-dialkoxyethylamine compound. SOLUTION: The method for producing the compound represented by formula (2) (wherein, ring X represents an aromatic ring which may be substituted; R<SP>2</SP>represents a hydrogen atom, an alkyl which may be substituted or an aryl which may be substituted; R<SP>3</SP>represents a secondary alkyl; and R<SP>4</SP>represents a hydrogen atom or an alkyl) or its salt is characterized as follows. A compound represented by formula (1) (wherein, R<SP>1</SP>represents an arylsulfonyl or the like which may be substituted) is treated with a base in the coexistence of a secondary alcohol R<SP>3</SP>OH and then treated with an acid in the presence of an alcohol R<SP>4</SP>CH<SB>2</SB>OH.
