Participants

Reaction Steps

A solution of 2-chloro-2,3-dihydro-3,3-dimethylbenzofuran-5-yl methanesulphonate (14g, 0.05 mole) in 1,1-dimethylpropanol (50 ml) was boiled under reflux for 41/2 hours. After cooling, the solution was taken into ether (250 ml), washed with dilute aqueous sodium hydroxide solution (twice) and with water (twice) and dried over sodium sulphate. The solvent was then distilled off under reduced pressure to give 2,3-dihydro-3,3-dimethyl-2-(1,1-dimethylpropoxy)benzofuran-5-yl methanesulphonate (7g, 43% yield) as a pale yellow oil.
