Methyl iodide → Methyl 6-bromopyridine-2-carboxylate

Participants

Reaction Steps

6-bromopicolinic acid (1.99 g) in DMF (10 mL) was treated with potassium carbonate (1.40 g) and then methyl iodide (4 mL) at room temperature for 20 h. The reaction mixture was diluted with dichloromethane (60 mL) and filtered. The filtrate was extracted with brine (twice), dried (MgSO4), and concentrated under vacuum to give methyl 6-bromopicolinate as a pale yellow solid (1.75 g).
