3-Cyanopyridine → HCID 10012236, compound

Participants

Reaction Steps

3-cyanopyridine (10.0 g, 96.1 mmol) was dissolved in isopropanol (50 ml). Sodium hydride (0.23 g, 9.6 mmol) from which oily matters had been removed by washing with ether was added to the solution, and the mixture was stirred at room temperature for 3 hours. After the reaction was completed, acetic acid (0.64 g, 10.7 mmol) was added to neutralize the reaction solution, and the solution was concentrated under reduced pressure. After concentrating the solution, diethyl ether (80 ml) was added to the concentrated residue, and insoluble products were removed by filtration. The filtrate was concentrated under reduced pressure, and hexane (80 ml) was added to the concentrated residue, and depositing unreacted 3-cyanopyridine.was removed by filtration. The hexane solution was then concentrated under reduced pressure to give the crude product of isopropyl 3-pyridinecarboximidate as a pale yellow oil in a yield of 5.68 g.
