Reaktionsschritte
Into a stirring solution of methyl-2-methyl-6-nitrobenzoate (3.9 g, 20 mmols) in 50 mL CCl4 anhydrous, N-bromosuccinamide (3.56 g, 20 mmols), and benzoylperoxide (25 mg, 0.10 mmols), was added. The reaction mixture was heated under reflux for about 24 hours. TLC developed in EtOAc/Hex 1:9 mixture showed formation of new product. The CCl4 was evaporated and on leaving a viscous product at RT, light yellow crystals of product were separated. The product was purified by flash silica gel column eluted with Hex/EtOAc. 9:1 mixture to give 3.0 g light yellow crystals (70%). A small portion of dibrominated product was also separated. 1H NMR in CDCl3 confirmed the product as methyl-2-bromomethyl-6-nitrobenzoate.
