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. Recommanded Product: Acetylpyrazine
General procedure: General procedure: 8-Hydrazinocaffeine (3) (112 mg;0.5 mmol) and carbonyl compound (1 mmol; 2 eq.) were mixedin ethanol (20 mL, containing 0.2 mL of acetic acid) and heated at 75 omicronC for 3 days. After cooling down, reaction mixture was evaporatedto dryness and solid residue was suspended in diethyl ether(50 mL), filtered off, washed with additional portion of diethylether (3 25 mL) and dried in vacuo at 50 C to obtain the hydrazone.
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.
