2.5 g of crude 2-allyloxyacetic acid are introduced into 40 ml of toluene, and 4.7 g (30 mmol) of 9-decen-1-ol and 0.38 g (2.0 mmol) of p-toluenesulfonic acid are added. The mixture is then heated with a water separator until visible amounts of water no longer separate out. The mixture is then cooled, and the organic phase is washed once with saturated NaHCO3 solution, dried over Na2SO4 and filtered, and the product is freed from the solvent. Flash chromatography (cyclohexane/EtOAc=20:1, Rf=0.29) gives 3.1 g (62%) of dec-9-enyl 2-allyloxy-acetate as a colorless oil.
