To a solution of ethyl salicylate (100 g, 0.602 mol) in DMF (400 ml) was added K2CO3 (150 g), followed by the dropwise addition of allyl bromide (87.5 g, 0.723 mol). The reaction mixture was then heated on a steam bath for 2 hours, the K2CO3 was removed by filtration and the reaction mixture was poured into water and extracted with ethyl acetate (3×300 ml). The organic layer was washed with brine, and dried over MgSO4, and the solvent was removed to afford 122 g (98%) of ethyl 2-(2-propenyloxy)benzoate.
