Versuchsvorschrift
A mixture of (2-fluoro-6-methoxy-3-methylphenyl)boronic acid (200 mg, 1.087 mmol) was cooled to 0° C. and BBr3 (0.308 mL, 3.26 mmol) was added. The mixture was then stirred at rt for 2 h. It was then poured into ice and extracted with EtOAc. The organic layer was dried over MgSO4, filtered and concentrated to obtain 185 mg (95%) of the desired product as a white solid. 1H NMR (400 MHz, CDCl3) δ 8.57 (s, 1H), 7.25-7.15 (m, 1H), 6.71-6.61 (m, 1H), 5.76-5.53 (m, 2H), 2.20 (d, J=2.0 Hz, 3H). LCMS (M+23)=193.
