2-Acetylpyridine → HCID 86589147, compound

Participants

Reaction Steps

A mixture of 2-acetyl pyridine (1.00 g, 8.26 mmol) and 1-phenyl-2-hydrazinobenzimidazole (1.85 g, 8.26 mmol) in 20 ml of methanol is stirred at room temperature for 2 days after the addition of 6 drops of glacial acetic acid. The reaction is monitored by means of thin layer chromatography (Polygram Sil G/UV254 prefabricated foils; eluting agent: CH2Cl2:MeOH (12:1)). Subsequently, the reaction mixture is diluted with distilled water until a precipitate forms and stored for 24 hours in the refrigerator at approximately 5° C. The precipitate is filtered, washed several times with 50% methanol, and dried. The product is recrystallized from a mixture of methanol and water. Yield: 1.35 g (50% of theory).
