<p>Disclosed is a method for commercially producing a 2-alkenyl-3-aminothiophene derivative, which is useful as an intermediate for agricultural chemicals, at low cost. Specifically disclosed is a method for introducing an alkenyl group into the 2-position of a 3-aminothiophene derivative by reacting a 3-aminothiophene derivative represented by the general formula (2) below or a salt 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)-(3d) which are useful as an intermediate for agricultural chemicals.</p> |
