Reaction Steps

A mixture of (4-chloro-2-methoxy-5-methylphenyl)boronic acid (100 mg, 0.499 mmol) in DCM (2 mL) was cooled to 0° C. and BBr3 (0.142 mL, 1.497 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 150 mg (97% yield, 60% pure) of the desired product as a brown solid. 1H NMR (400 MHz, CDCl3) δ 7.59 (br. s., 1H), 7.11 (br. s., 1H), 4.30-4.11 (m, 1H), 4.01 (br. s., 1H), 2.37 (s, 3H).
