Reaktionsschritte

2-(N-Monomethylamino)pyridine (98, 1.00 g, 5.55 mmol) was dissolved in dichloromethane (20 mL) and a 1 M iodine monochloride (ICl, 6.10 mL, 6.10 mmol) dichloromethane solution was slowly added at 0° C., and stirred for 30 minutes. To the reaction mixture was added a 10% aqueous solution of sodium sulfite (Na2S2O3) and organic compounds were extracted with dichloromethane and evaporated after a treatment with sodium sulfate. Purification was performed by column chromatograph to give the target compound 2-(N-monomethylamino)-5-iodopyridine (99, 800 mg, 62%) as a yellow solid.
