Procedure

To a stirred solution of o-(t-butyl)-phenol (11.3 g; 75 mmol) in acetone (150 ml) is added allyl bromide (10.9 g, 1.2 equiv.) and anhydrous K2CO3. After stirring 18 hr at reflux, the reaction is added to water (200 ml) and extracted with 3×150 ml portions of petroleum ether. The combined organic layers are dried (MgSO4), filtered, and concentrated in vacuo to give the crude product, which is purified by silica gel (sg) chromatography (hexane elution) to yield 1-prop-2-enyloxy-2-t-butylbenzene (11.6 g; 81% yield).
