摘要
PROBLEM TO BE SOLVED: To provide a method by which only one tautomer of a 4-pyridone is selectively taken out or fixed as inclusion crystal, a chemical reaction method for using the inclusion crystal, a method for fixing a 2-pyridone, with which one tautomer of the 2-pyridone is included with diphenic acid and photodimerized and a chemical reaction method for using the inclusion crystal.;SOLUTION: The method for fixing the pyridone comprises including one isomer of the 4-pyridone which is represented by formula (R1 and R2 may be the same or different and are each a hydrogen atom, a halogen atom, a 1-10C straight-chain or branched alkyl group or a 1-10C straight-chain or branched alkoxy group; X is an oxygen atom or a sulfur atom) and in which tautomers exist with a host compound and fixing the pyridone.;COPYRIGHT: (C)2004,JPO
