Procedure

The product prepared above was hydrogenated following the general procedure described in Example I. For the reaction, 2.1 g 3-heptylidene-5-ethyldihydro-2(3H)-furanone (0.010 mole) was combined with 0.1 g 5% palladium on carbon and 5 ml ethanol and hydrogen gas slowly introduced for 1.5 hours. Upon removal of the catalyst and evaporation of the solvent, 2.0g (97% assay by GLC; 95% yield) 3-heptyl-5-ethyldihydro-2(3H)-furanone was recovered.
