Reaction Steps
Combine 5-bromomethyl-2-fluoro-4-iodo-pyridine (0.9 g, 2.85 mmol), nitromethane (15 mL, 278 mmol), silver tetrafluoroborate (721 mg, 3.7 mmol), and dimethylformamide (5 mL) in a round bottom flask. Stir the mixture overnight at room temperature. Add sodium carbonate (1.81 g, 17.1 mmol) and methanol (10 mL) into the mixture. Stir at room temperature for another 4 hours. Dilute the reaction mixture with chloroform, and wash with water and saturated aqueous sodium chloride. Separate the organic layer from the aqueous layer and dry over MgSO4. After filtration, evaporate the organic solvent in vacuo to give the crude product. Purify the crude with flash column chromatography (eluted with 10% methanol in dichloromethane) to give the desired product (0.6 g, 83%). MS (ES) m/z 254 [M+1]+.
