Acetic Acid → Methyl furan-2-carboximidate

참여 물질

반응 단계

2-Cyanofuran (4.50 g, 48.3 mmol) was dissolved in methanol (25 ml), and sodium methoxide (130 mg, 2.4 mmol) was added under ice-cooling. The mixture was stirred while the temperature is slowly raised up to room temperature for 2 hours. After the reaction was completed, acetic acid (0.16 g, 2.6 mmol) was added to neutralize the reaction solution, and the solution was concentrated under reduced pressure. Diethyl ether (100 ml) was added to the concentrated residue, and insolubles were removed by filtration. The filtrate was concentrated under reduced pressure to give the crude product of methyl 2-furancarboximidate (6.0 g) as a pale yellow oil.
