2-Bromopropane → 2,3-Dimethyl-1-(2-propyl)oxybenzene

反応手順

To a stirred solution/suspension of 2,3-dimethylphenol (10 g) and potassium carbonate (6.8 g) in acetone (150 ml) at reflux was added 2-bromopropane (46 ml) drop-wise over 30 min. The solution was heated at reflux for 4 days. After cooling, the solvent was evaporated and the residue was dissolved in ether and water. The ether phase was separated and was worked up according to the general procedure. Column chromatography on silica gel (eluent:ethyl acetate/heptane 1:19) afforded pure 2,3-dimethyl-1-(2-propyl)oxybenzene (13.2 g) as a mobile, slightly brown oil which was used without further purification.
