Reaktionsschritte

To a mixture of methyl 5-methylpicolinate (1.25 g; 8.27 mmol) in carbon tetrachloride (45 mL) was added N-bromosuccinimide (1.78 g, 9.92 mmol) and benzoyl peroxide (0.205 g; 0.827 mmol). The mixture was refluxed for 18 hours and the resulting suspension was concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel (eluent 0 to 8% ethyl acetate in dichloromethane) to 0.450 g (24%) of methyl 5-(bromomethyl)picolinate as a beige solid.
