Compound containing pyridine ring and method for producing halogenated picoline derivative and tetrazolyloxime derivative

摘要

Disclosed is a compound containing pyridine ring that can be advantageously synthesized industrially. Also disclosed is an industrially advantageous method for producing the compound represented by formula (1) containing a pyridine ring, this compound being useful as an intermediate for producing tetrazolyloxime derivatives that exhibit bactericidal activity. The method also industrially produces 2-substituted amino-6-halomethylpyridine derivatives and tetrazolyloxime derivatives advantageously. (In the formula, R
