Methyl iodide → 2-(Methylthio)thiazolo[5,4-b]pyridine

참여 물질

반응 단계

To the suspension of thiazolo[5,4-b]pyridine-2-thiol (168 mg, 1.0 mmol) in THF (3.3 ml) was added potassium carbonate (193 mg, 1.4 mmol), followed by iodomethane (68.2 μl, 1.1 mmol) dropwise. The reaction mixture was stirred at room temperature for 16 h. Additional iodomethane were mixed in (40 uL) and stirred at room temperature for another 3 h. LCMS showed reaction was complete. The crude reaction mixture was suspended in ethyl acetate and washed with water, then brine, dried over sodium sulfate, filtered, and concentrated to give 2-(methylthio)thiazolo[5,4-b]pyridine (182 mg, 1.0 mmol, 100% yield) as a tan solid.
