Reaction Steps
To a solution of ethyl 3-hydroxybenzoate (20 g, 0.13 mol) in dichloromethane (200 ml) were added isobutene (about 30 g) and conc. sulfuric acid (0.5 ml), and the mixture was left for 2 days. The reaction solution was washed with saturated aqueous sodium hydrogen carbonate solution, dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The residue was purified by silica gel chromatography (hexane:ethyl acetate=10:1) to give the objective substance (17.3 g, 63%) as an oil.
