Reaction Steps

The obtained 2-(N-monomethylamino)-5-iodopyridine (99, 1.00 g, 4.27 mmol), potassium carbonate (2.95 g, 21.36 mmol) and iodomethane (145 mg, 8.546 mmol) were dissolved in dimethylacetamide (30 mL), and the reaction mixture was heated at 90° C. for 24 hours, followed by adding water. Organic compounds were extracted with ethyl acetate and evaporated after a treatment with sodium sulfate. Purification was performed by column chromatograph to give the target compound 2-(N,N-dimethylamino)-5-iodopyridine (100, 603 mg, 57%).
