Procedure
To a suspension of 2-chloro-5-methylphenol (10.0 g, 0.07 mol) and potassium carbonate (11.7 g, 0.08 mol) in acetonitrile (200 mL) at 82° C., was dropwise added a solution of allyl bromide (9.6 mL, 0.11 mol) in acetonitrile (50 mL). The mixture was reflux overnight. Once at room temperature, the mixture was filtered and the precipitate rinsed with diethyl ether. The filtrate was then concentrated in vacuo. The residue was dissolved in diethyl ether (250 mL) and washed with a 2N sodium hydroxide solution (150 mL). The organic layer was dried over sodium sulfate and concentrated in vacuo to provide 1-chloro-4-methyl-2-(prop-2-en-1-yloxy)benzene (7a) (12.72 g, 0.07 mol, 99%) which was used without further purification.
