Reaktionsschritte

3-Bromo-4-methoxyphenylacetic acid (1.3 g, 5.6 mmol) was heated in a solution of hydrogen bromide (3 mL) and acetic acid (3 mL) at 100° C. overnight. The mixture was then partitioned between EtOAc and H2O, and the aqueous layer was separated and extracted with EtOAc. The combined organic layers were washed with brine, dried over MgSO4, filtered, and concentrated to give the title compound.
