Abstract
Official abstract text for this publication.
Disclosed is a compound containing a pyridine ring that can be synthesized in an industrially advantageous manner, and is useful as an intermediate for producing tetrazolyloxime derivatives that exhibit fungicidal activity (wherein R 0 represents a C 1-6 alkoxy group, C 1-6 alkoxy-C 1-6 alkoxy group or the like, R 1 represents a C 1-2 alkoxycarbonyl group, acetyl group or the like, Z represents a halogen atom, cyano group or the like, X represents a halogen atom, and n represents an integer of 0 to 3), and industrially advantageous production methods for producing 2-substituted amino-6-halomethylpyridine derivatives and tetrazolyloxime derivatives.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a brominated picoline derivative represented by formula (6), the method comprising reacting a brominated picoline derivative represented by formula (4) and/or formula (5), a phosphite ester, and a base in an organic solvent, wherein R 1b represents an unsubstituted or substituent-containing alkoxycarbonyl group, R 2b…
