Procedure
To 13.0 g (84.92 mmol) 3-chloro-2-methylanisole in 80 ml CCl4 at reflux were added 0.4 g dibenzoyl peroxide and then, subsequently and portion-wise, a mixture of 15.2 g N-bromosuccinimide and 0.4 g dibenzoyl peroxide. After completion of reaction the mixture was evaporation-concentrated, the residue was dissolved in dichloromethane, was sequentially washed with water and saturated NaCl solution, was dried over MgSO4, was filtered and again evaporation-concentrated. 20.8 yellow oil.
