Abstract
PURPOSE: To obtain the titled compound useful as an intermediate raw material for medicines and agricultural chemicals efficiently, industrially and advantageously, by reacting a specific furylaldehyde with chlorine in the presence of a catalyst which is a radical initiator or by the irradiation with ultraviolet light.
CONSTITUTION: A furylaldehyde of formulaIis reacted with chlorine in the presence of a catalyst which is a radical initiator, e.g. potassium persulfate, or by irradiation with ultraviolet light. After confirming the disappearance of the furylaldehyde, the reaction mixture is distilled under reduced pressure to give the aimed compound of formula II. The use of a solvent, e.g. benzene, facilitates the adjustment of the reaction rate, or removal of the heat of reaction, etc.
EFFECT: The handling is easily carried out due to the liquid reactants as opposed to the conventional reaction in which the furancarboxylic acid is handled in the solid state.
