    摘要: An object of the present invention is to provide an industrially advantageous method for producing uracil compound, which is a production intermediate of a 2,6-dioxo-3,6-dihydropyrimidine compound, and ureidomethylene compound applicable as a raw material for uracil compounds. The present invention is characterized in that uracil compound, which is a production intermediate of a 2,6-dioxo-3,6-dihydropyrimidine compound, is produced by subjecting a compound of formula (II) below or a salt thereof to chemical reaction in the presence of an organic base or an inorganic base. In formula (II), X1 represents a hydrogen atom or a substituted or unsubstituted C1-6 alkyl group, X2 represents a hydrogen atom or a substituted or unsubstituted linear C1-6 alkyl group, etc., R1 represents a hydrogen atom or a substituted or unsubstituted C1-6 alkyl group, etc., R2 represents a hydrogen atom or a substituted or unsubstituted C1-6 alkyl group, and R3 represents a substituted or unsubstituted C1-6 alkyl group, etc.
