Abstract
PURPOSE: A readily available compound from 5-hydroxymethyl-2-furfural is subjected to catalytic hydrogenation in the presence of Pd, Rh catalyst to produce the titled compound used as a synthetic intermediate of agricultural chemicals or perfumes readily in high yield.
CONSTITUTION: A compound of formula I [R is R'-O (R' is alkyl, aryl) or group of formula II] is subjected to catalytic hydrogenation in the presence of a catalyst of Pd, Rh to give 5-methyl-2-furfural. Further, a base, such as pyridine or sodium hydroxide is added and catalytic hydrogenation is effected to inhibit side-reactions and increase the selectivity to 5-methyl-2-furfural.
