A mixture of 3,7-dimethyl-4-hydroxy-6-octen-1-ol (5.06 g, 29 mmole), acetic anhydride (3.06 g, 30 mmole), pyridine (4.75 g, 60 mmole) and ether (100 ml) is stirred at room temperature for 16 hours. The resulting mixture is treated with ether (200 ml) and washed with saturated cupric sulfate solution (2×100 ml). The organic phase is dried (Na2SO4) and evaporated in vacuo to give 8-acetoxy-2,6-dimethyl-5-hydroxy-2-octene as a colorless oil (2.27 g, 45%).
