Synthetic Route of 2075-46-9<\/a>,Some common heterocyclic compound, 2075-46-9, name is 4-Nitro-1H-pyrazole, molecular formula is C3H3N3O2, 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.<\/p>\n

Step2:[00394] To a stirred mixture of iron (1.68g, 30 mmol), ammonium chloride (540mg, 10 mmol), water (2ml_) and ethanol (8ml_) at 800C was added 4-nitro-1 H-pyrazol (1 .13g, lOmmol) in portions. After completion of addition, the mixture was stirred at 800C for additional 2 hours. After cooling to room temperature, the mixture was diluted with ethyl acetate, and the resultant mixture was filtered through a pad of celite. The filtrate was concentrated to afford the crude title compound which was used at next step without further purification. MS (ES) [M+H]+ expected 84.0, found 84.0.<\/p>\n

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 4-Nitro-1H-pyrazole, its application will become more common.<\/p>\n
