Reaction Steps
To a chloroform (15 ml) solution of 4-acetoxy-2-allyl-3,5,6-trimethylphenol [2.0 g (8.5 mmol)] was added dropwise while stirring, bromine [1.36 g (8.5 mmol)]. To the mixture was then added triethylamine (0.3 ml), which was heated for two hours under reflux. The reaction mixture was cooled, washed with water, dried and then concentrated. The concentrate was crystallized from hexane to obtain 5-acetoxy-2-bromomethyl-4,6,7-trimethyl-2,3-dihydrobenzofuran [2.5 g (yield 93.2%)].
