Abstract
PURPOSE: To prepare the titled substance useful as an intermediate of pesticides and pharmaceuticals, in high yield and selectivity, by reacting 5-chloromethylfurfural with molecular hydrogen in an organic solvent such as amides, ethers, esters, etc. in the presence of Pd catalyst.
CONSTITUTION: The titled substance is prepared by reacting 5-chloromethylfurfural with molecular hydrogen in the presence of Pd catalyst. The catalyst may be supported or unsupported, and its amount is 0.001W1mol per 1mol of the raw material in the case of batch reaction. The reaction is carried out using 0.5W10pts.wt., based on 1pt.wt. of the raw material, of an organic solvent selected from amides, ethers, esters (e.g. DMF, diethyl ether and methyl formate) or their mixture, at 10W80°C.
