57% | With potassium carbonate In ISOPROPYLAMIDE at 90℃; for 24 h; | 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, 57percent).1H NMR (400 MHz, CDCl3) δ 3.08 (s, 6H), 6.34 (d, J=8.4 Hz, 1H), 7.60 (dd, J=8.8, 2.4 Hz, 1H), 8.27 (d, J=2.4 Hz, 1H); 13C NMR (100 MHz, CDCl3) δ 38.1, 105.9, 107.1, 139.2, 148.3, 157.7. |

2086 mg | Stage #1: With sodium hydride In N,N-dimethyl-formamide; mineral oil at 20℃; for 0.5 h; Inert atmosphere; Cooling with ice Stage #2: Cooling with ice |
Under an argon atmosphere, after a N,N-dimethylformamide solution (20 mL) of 5-iodo-2-aminopyridine (11) (2200 mg, 10.0 mmol) was cooled with ice, sodium hydride (60percent oil, 1200 mg, 30.0 mmol) was added thereto. The reaction liquid was heated to room temperature, and stirred for 30 minutes. The reaction liquid was cooled with ice, and, after methyl iodide (4258 mg, 30.0 mmol) was added thereto, the reaction liquid was heated to room temperature. After the disappearance of the raw material, the reaction liquid was added in water and stirred, and the organic layer was extracted with ethyl acetate. After the organic layer was washed with water and saturated saline water and dried with anhydrous sodium sulphate, the solvent was distillated under reduced pressure. By refining the residue by column chromatography (developing solvent: heptane/ethyl acetate = 99/1 → 24/1), 2086 mg of the title compound (12) was obtained. |
