Dichloromethane → Methyl 2-(bromomethyl)-6-chlorobenzoate

참여 물질

반응 단계

A mixture of methyl 2-chloro-6-methylbenzoate (3.0 g, 16.2 mmol), N-bromosuccinimide (3.0 g, 17.0 mmol), and benzoyl peroxide (catalytic) in anhydrous carbon tetrachloride (50 mL) was stirred at reflux overnight. Dichloromethane (50 mL) was added after cooling to room temperature. The mixture was extracted with 1 N NaOH (2×100 mL). The organic layer was recovered, dried over MgSO4, filtered, and evaporated, and the residue was dried in vacuo, affording methyl 2-(bromomethyl)-6-chlorobenzoate (4.06 g, 95% yield), which was used without further purification.
