Some common heterocyclic compound, 22047-25-2, name is Acetylpyrazine, molecular formula is C6H6N2O, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. category: Pyrazines
General procedure: A 100 mL round-bottom flask charged with 2-acetylpyrazine (1.47 g, 2 mmol) was added MeOH (30 mL), KOH pellets (0.675 g,2 mmol) and water (2 mL). The resulting mixture was stirred for10 min and then added corresponding n,n?-dimethoxybenzaldehydes (1.0 g, 1 mmol) and ammonium solution (6 mL) was added slowly stirring at room temperature for 4 h, a white precipitate obtained was filtered, washed with MeOH and diethyl ether. The crude products on recrystallization in a mixture of CHCl3:MeOH (1:1) gave white crystals of desired compounds, 1-4.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 22047-25-2, its application will become more common.
