## Abstract

Provided are novel pyridine compounds represented by the following formula (7): wherein R1 and R4 may be the same or different and are each a linear or branched alkyl group having 1 to 4 carbon atoms; R2 and R5 are hydrogen atoms, or may be the same or different and are each a halogen atom, lower alkyl group or lower alkoxy group; R3 is a linear or branched alkyl group having 2 to 12 carbon atoms; R6 is a linear or branched alkyl group having 1 to 18 carbon atoms; and Z is a chlorine atom, bromine atom or iodine atom or an OSO2R7 group in which R7 is a lower alkyl group or a substituted or unsubstituted phenyl group. Also provided is their production process, which can easily provide them at low cost from readily-available pyridine compounds as starting raw materials.

## Claims

### Claim 1

A microbicidal pyridine compound represented by the following formula (8) or formula (9):
wherein Z is a chlorine atom, bromine atom or iodine atom or an OSO2R1 group in which R1 is a lower alkyl group or a substituted or unsubstituted phenyl group.

### Claim 2

A microbicidal pyridine compound represented by the following formula (10):
wherein R is a —(CH2)9CH3 group or a —(CH2)11CH3 group, Z is a chlorine atom, bromine atom or iodine atom or an OSO2R1 group in which R1 is a lower alkyl group or a substituted or unsubstituted phenyl group.
