  • Patent number: 6342606
    Abstract: A pyridine alcohol derivative represented by General Formula III (where A represents a divalent organic group which may contain one to three oxygen atoms, nitrogen atoms and/or sulfur atoms, wherein A may form a 5-, 6-, 7-, or 8-membered ring together with two bonded carbon atoms, where said ring may form a condensed ring with one or more additional rings; R6 represents a hydrogen atom, —CHR1R2, or an alkenyl group, an aryl group or an aralkyl group which may be substituted; R1 and R2 each independently represent a hydrogen atom or a hydrocarbon group which may be substituted; and R represents a hydrogen atom, an alkyl group, an alkenyl group, an aryl group or an aralkyl group which may be substituted), is produced by: reacting a pyridine ester derivative represented by General Formula I-1
