Versuchsvorschrift
A solution of N-bromosuccinimide (10 mmol) in 8 mL of DMF is added dropwise to a solution of 1-(5-chloromethyl-2-hydroxy-phenyl)-ethanone 211 (10 mmol) in 20 mL DMF and the resulting mixture is stirred for 12-18 h. The solvent is evaporated under reduced pressure and the residue is diluted with water resulting in the formation of a solid. The solid is isolated and recrystallized from ethanol to yield 1-(3-Bromo-5-chloromethyl-2-hydroxy-phenyl)-ethanone 212.
