Abstract

PURPOSE: To obtain the titled compound which is an intermediate for medicines, agricultural chemicals, etc., in high selectivity without side reactions, by reacting 5-chloromethylfurfural easily preparable from a glucide compound as a raw material with molecular hydrogen in the presence of a catalyst in an organic solvent containing a basic additive.
CONSTITUTION: 5-Chloromethylfurfural prepared from a glucide compound e.g. a monosaccharide or disaccharide, as a raw material is reacted with molecular hydrogen in an organic solvent, inert to the reaction, and containing a basic additive, e.g. benzene or chloroform, in an amount of 1W10pts.wt. based on the raw material in the presence of a palladium catalyst at 100°C or below, preferably about -10W+80°C, to give the aimed compound. Triethylamine or sodium carbonate, is preferred as the basic additive, and the amount thereof is preferably 0.1W5mol, mole preferably 0.3W1.5mol, based on the raw material.
