22047-25-2, name is Acetylpyrazine, belongs to pyrazines compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Application In Synthesis of Acetylpyrazine
General procedure: Ketone (20 mmol) (2-acetylpyridine, 2-acetylthiazole or 2-acetylpyrazine)was added to a solution of aldehyde (10 mmol) (4-methoxybenzaldehyde,4-methoxy-1-naphthaldehyde or 6-methoxy-2-naphthaldehyde) in EtOH (75 mL). KOH (1.54 g, 27.5 mmol) and NH3(aq)(35 mL) were then added. The solution was stirred at room temp. for 24 h. The solid was collected by filtration and washed with H2O. Recrystallization from ethanol (L1,L4, L7) or toluene (L2, L3, L5, L6, L8,L9) afforded a crystalline solid.
The synthetic route of 22047-25-2 has been constantly updated, and we look forward to future research findings.
