Procedure

600 g of 1-acetoxy-5-isopropoxy-3-methyl-2-pentene are hydrogenated in 2000 cc of ethanol with 60 g of Raney nickel at 71 atmospheric pressure and 70°C for 24 hours. After this period, another 30 g of catalyst are added and hydrogenation is effected under the same conditions for a further 20 hours. After filtration, the reaction mixture is evaporated and the residue is distilled. Gas-chromatographically pure 1-acetoxy-5-isopropoxy-3-methyl-pentane is obtained. B.P.: 106°-108°/12 mm Hg. nD20 = 1.4286
