Versuchsvorschrift

To a solution of methyl(2-hydroxyphenyl)acetate (14.0 g, 84.3 mmol) in 100 mL of DCM was added diisopropyl-amine (1.70 g, 16.8 mmol) and NBS (15 g, 84.2 mmol) at 0° C. The mixture was stirred at 0° C. for 1 h. The reaction was poured into 1N HCl, extracted with DCM, and concentrated to give crude methyl(3-bromo-2-hydroxyphenyl)acetate.
