How is Bromo(2,3-dimethylphenyl)magnesium (CAS: 134640-85-0) typically synthesized?

Bromo(2,3-dimethylphenyl)magnesium is commonly synthesized via the Grignard reaction. Typically, bromobenzene or bromo-2,3-dimethylbenzene is reacted with magnesium in an ether solvent. The reaction requires careful control of temperature and the use of a drying agent to prevent water from reacting with the magnesium. The product is a colorless or pale yellow liquid.
