A process for producing a pyridine derivative, which comprises reacting an azametallacyclopentadiene represented by formula (I) with an alkyne in an organic solvent containing a complex of a transition metal such as Ni(II). (In formula (I), M represents an early transition metal, e.g., Zr, Ti, or Hf; L represents a cyclopentadienyl, indenyl, fluorenyl, azulenyl, hydrocarbon-oxy, amide, acetylacetonato, or carboxy group, a phosphine ligand, an amine ligand, an ether ligand, or a ligand comprising two or more of these bonded to each other through an appropriate crosslinking group; n is an integer of 1 to 4; and R1, R2, R3, R4, and R5 each represents C1-20 (substituted) alkyl, alkenyl, an aromatic group, silyl, alkoxy, or an ester group.)
