To a solution of (2,4-dimethyl-1-vinylcyclohex-3-enyl)methanol (3.50 g, 21.1 mmol), triethylamine (3.83 g, 38 mmol) and a catalytic amount of DMAP in Et2O (30 ml) was added Ac2O (3.22 g, 31.6 mmol). The mixture was stirred for 5 h, poured on water and extracted with Et2O. The combined organic layers were washed with water and brine, dried and evaporated in vacuo. The residue was distilled bulb-to-bulb to yield (2,4-dimethyl-1-vinylcyclohex-3-enyl)methyl acetate (3.81 g, 86%) as a colorless oil.
