Procedure
Methyl 5-[4-acetonylphenoxymethyl]furan-2-carboxylate, ethylene ketal (12.5 g) was hydrogenated at ambient temperature and pressure, in methanol, in the presence of 5% rhodium on alumina. The reaction mixture was filtered and evaporated to an oil which was purified by column chromatography on silica gel. Elution with chloroform gave methyl 5-[4-acetonylphenoxymethyl]tetrahydrofuran-2-carboxylate, ethylene ketal.
