Versuchsvorschrift

2,6-Dimethylphenol (1.22 g) is added to a mixture of powdered potassium hydroxide (2.24 g) in dimethylsulfoxide (20 ml). Then 3-bromopropane (2.42 g) is added at 20°-25° and stirred for 0.5 hr. The mixture is diluted with water (100 ml) and extracted with methylene chloride (3×). The organic extracts are washed with water (2×) and then with saline, dried over sodium sulfate and concentrated under reduced pressure to give 1-allyloxy-2,6-dimethylbenzene.
