PROBLEM TO BE SOLVED: To provide a process for preparing 3-phenyl(thio)uracils and -dithiouracils.SOLUTION: In the process for preparing 3-phenyl(thio)uracils and -dithiouracils, carbamates having X, X, Ar, and A in formula and enamines having X, R, R, and Rare made to react with each other (in formula, X, X, and Xrepresent oxygen or sulfur, Ar represents a phenyl residue, A represents an amino residue, and R, R, and Rrepresent hydrogen or the like).
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing 2-methoxyimino-2-[2-(chloromethyl)phenyl]acetic acid derivatives. SOLUTION: The invention relates to a method for producing 2-chloromethylphenyl acetic acid derivatives of formula I, in which X represents 1-4C alkoxy or methylamino, by cleaving the ether bonds in compounds of formula II, in which R represents 1-4C alkyl, 1-4C alkoxy, 1-2C alkyl halide, 1-4C alkylcarbonyl, 1-4C alkylcarbonyloxy, halogen, nitro or cyano. The inventive method is characterized in that the transformation takes place in the presence of hydrogen chloride and an inert solvent, and in that a catalyst selected from the group consisting of iron, indium and halogenides, oxides or triflates thereof is added to the reaction mixture.
