Disclosed is a method for commercially producing 2-alkenyl-3-aminothiophene derivatives, which are useful as intermediates for agricultural chemicals, at low cost. Specifically disclosed is a method for introducing alkenyl groups into the 2-position of 3-aminothiophene derivatives by reacting 3-aminothiophene derivatives represented by the general formula (2) below or salts thereof with a ketone represented by the general formula (1) below without using a protecting group. Also specifically disclosed are 2-alkenyl-3-aminothiophene derivatives (3a) to (3d) which are useful as intermediates for agricultural chemicals,
