PROBLEM TO BE SOLVED: To provide an improved method for producing tolterodine and fesoterodine. SOLUTION: The method for producing a compound represented by formula (I) [wherein, Y is a CH<SB>3</SB>, a Br or the like] is provided. The compound represented by formula (I) is obtained by reacting a compound represented by formula (II) äwherein, OX is a hydroxy or an O<SP>-</SP>M<SP>+</SP>[wherein, M<SP>+</SP>is a cation such as an Li<SP>+</SP>]; and Y is as defined in formula (I)} with trans-cinnamaldehyde.
