Water → 2-Allyloxy-2',6'-dichloro-5-fluorobiphenyl

Participants

Reaction Steps

To a solution of 2′,6′-dichloro-5-fluorobiphenyl-2-ol (11.63 g, 45 mmol) in DMF (150 mL) was added allyl bromide (5.8 mL, 67.5 mmol) and potassium carbonate (18.6 g, 135 mmol) at room temperature. The resulting mixture was stirred at room temperature overnight and poured into water. The mixture was extracted with methylene chloride and washed with water. The solvent was removed under vacuum. Chromatography with 0–30% ethyl acetate in hexanes afforded 12.7 g (94%) of 2-allyloxy-2′,6′-dichloro-5-fluorobiphenyl as a light yellow oil. MS (EI) m/z 296 (M+).
