3,5-Diethyl-5,6-dihydro-2H-2-pyranol obtained in Example 3 (5 g) was put into a 100-ml autoclave together with 0.25 g of Raney nickel and 0.5 ml of water, followed by stirring at 120° C. for 5 hours at a hydrogen pressure of 30 kg/cm2. After the catalyst was filtered off from the reaction mixture, water was distilled under reduced pressure to obtain 2,4-diethyl-1,5-pentanediol quantitatively.
