実験手順: A mixture of methyl 2-(bromomethyl)-6-chlorobenzoate (4.0 g, 15.6 mmol), diethylamine (5 mL, 48.1 mmol), and potassium carbonate (4.3 g, 31.2 mmol) in acetone (60 mL) was stirred at room temperature for 2 days. The solid material was removed by filtration. The filtrate was recovered, evaporated, and dried in vacuo, affording methyl 2-chloro-6-[(diethylamino)methyl]benzoate (3.97 g, 99% yield), which was used without further purification. The solid material was removed by filtration The filtrate was recovered evaporated dried in vacuo

実験手順: 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. at reflux overnight The mixture was extracted with 1 N NaOH (2×100 mL) The organic layer was recovered dried over MgSO4 filtered evaporated the residue was dried in vacuo
