Versuchsvorschrift

To a solution of 6-chloro-2′-methyl-biphenyl-2-ol (4.75 g, 21.7 mmol) in DMF (30 mL) was added potassium carbonate (4.5 g, 32.6 mmol) and allyl bromide (3.0 mL, 32.6 mmol) at room temperature. The resulting mixture was stirred at room temperature for 4 h. The mixture was extracted with ethyl acetate, washed with water and saturated sodium chloride, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. Purification by ISCO using a solvent gradient of O to 30% ethyl acetate in hexanes provided 5.6 g (100%) of 2-allyloxy-6-chloro-2′-methylbiphenyl as a light yellow oil.
