Definitions
- the present invention relates to a method for producing a pyridine derivative having a substituent having a heterocyclic structure at the 2-position.
- the pyridin derivative obtained by the present invention and substituted at the 2-position with a substituent having a heterocyclic structure is useful as a synthetic intermediate of an antifungal agent (US Pat. Nos. 5,693,611). No.).
